Focus Week 1 - January Patch

Submitted 23 January 2022 by Tarogato

Throughout this week we'll be adding builds to our database for each of the mechs that got significant quirk updates this month - the Nova, Linebacker, Black Knight, Battlemaster, and Blood Asp.

The Nova has always been a decent mech and so has not received many quirks that augment what it is already good it - red laser spam. It has received a slight armour buff to its side torsos which is the main weakness that has held this mech back from being a top choice. Most buffs focus on benefiting stock weapons and loadouts. The stock 12ERML build was already decent, and now it's actually rather good. Many ballistic builds which were previously worthless can now be run thanks to copious ammo and DPS quirks.

The Linebacker saw similar changes to the Nova. Mostly quirks that enable it to run ballistic quirks and a light smattering of durability where it was most needed.

With the Black Knight, previously the only variant really worth playing was the BL-6B-KNT due to its heat quirk which boosts raw damage output. Other variants of the Black Knight now have much stronger offensive quirks to compete more closely. Overall, the chassis has received a significant durability boost in the form of a having its structure boosts converted to armour - they are now a bit harder to crack open, which might elevate them out of trash tier.

The Battlemaster has been a rather mediocre mech for a long time now, really only excelling at ERLL trade yet still not being a top choice in that niche. Now all variants have durability quirks to help offset this mech's large profile. Offensively, pretty much every aspect of every variant has been improved and a lot of people will be testing to see if its enough to make this mech worth playing again.

The Blood Asp is already one of the better mechs in the game, so its strongest builds have not been buffed. Omnipods which were previously useless or overlooked have received boosts in efforts to bring them up to par with the chassis' previously preferred configurations.

Cauldon catch up and moving forward

Submitted 6 October 2021 by Tarogato

Ever since game balance has been taken over by The Cauldron, MWO has been in a constant state of flux. While The Cauldron is not done yet, most of what they set out to initially do has made it into the game by now and had some time to settle in. As things are solidifying, it's finally time for GrimMechs to reassess the ratings on our Tier Lists and play catch up with all the new builds people are running.

In the coming week, we'll be updating the list of builds that we consider S-tier mechs for General/QP. Visit our Discord server and leave us some recommendations for builds YOU think should comprise S-tier General and we'll consider them.

Build Database


While the Tier Lists have not been updated yet, we HAVE been adding builds to our Database. Check it out if you haven't recently, you can sort the table by Updated date to see what's new!

MechDB 2.0


All build links on the site have now been converted to MechDB 2.0 links. Thanks to Kill2Blit for helping us with this and working on the new update to his site! MechDB 2.0 is still a work in progress, so if you have any feedback regarding the new site, drop by the MechDB Discord to share your thoughts and suggestions.

GrimMechs Focus Weeks


Each week we'll choose one item to focus on and devote the week to discussing it on the GrimMechs Discord. This week we're taking suggestions for General/QP S-tier mechs, so head over there and let us know what mechs you think deserve to be rated as the best! In future weeks we may choose topics such as "SPL mechs" or "LPPC mechs" or "Marauder builds" and work on flushing out our Database and Tier Lists with each topic in turn.

2020 Update - Back in business!

Submitted 5 January 2021 by Tarogato

GrimMechs has gone a year and a half without updates. To be fair, you can say the same for Mechwarrior Online itself. But as the game's meta has evolved and settled over time, our tier list has grown more and more inaccurate.

A wonderful thank you to everyone who has continued to promoting and recommend the site. It pains me to see it popping up everywhere when it's become so inactive and out of date, so it's time to get working on it again!

- The General Tier List has been updated and will continue to be adjusted.
- Every single hero mech in the game now has at least one suggested build in the database.
- Nova Cat build guide added. Thanks to KhanCipher for submitting all the builds and doing some writing which I've appropriated.
- Incubus build guide has been live for a while now. Written by Tarogato.
- Adder build guide added. Written by Tarogato.

Most of these new entries have yet to be sorted onto the tier lists, that will happen soon!

May update - new features!

Submitted 23 May 2019 by Tarogato

Three new Build Guides are up, and these chasses have been added to our Tier Lists:
- Champion
- Marauder II
- Cougar
Coming soon: Mauler, Bushwacker, Hunchback, Fafnir, Wolfhound.

Rifleman IIC


We are polishing this Build Guide right now. Until it is made public, you can find our Rifleman IIC builds here.

MW5 pre-order variants


We have some optimal builds for these mechs in our database now. Check them out here:
- CPLT-C2
- WHM-9D
- MAD-9M
- KGC-001


Build Database


If you haven't checked it out recently, do visit the Database. Over the past two months, we've added our entire backlog of mech builds, so there's a decent list of mechs that goes beyond just what we have Build Guides for.

Filtering!


There are now buttons at the top of the Tier Lists and Database where you can filter and search by various categories. The filters are saved to the URL, so you can link other people directly to specific filtered views.

Build Codes!!!!


All builds now have an icon nearby where you can copy the Build Code to import directly into MWO. Some builds can be done on more than one variant of a chassis and you can choose which variant you want the code to be for. This feature is currently only supported by GrimMechs. =]

Direct linking in Guides


When you click on the name of a build or variant, you can copy the page URL to share a direct link with others.
So if I wanted to show you straight to this LB30 Black Widow, I can do that.


I want to sincerely thank Scuro for all his time, effort, and patience in working with me to code these new features.
I may turn the tiller, but Scuro is at the oars doing the thankless hardwork behind the scenes. So if you get a chance, thank him!

Update #1 - Dervish theorycraft?

Submitted 29 March 2019 by Tarogato

Most of our time this month has been spent on back-end shenanigans. Content injections will pick up as we wrap up our current internal projects. Thank Thor for Scurro and his continued unyielding efforts in building our inner-workings from the ground up.


Here's what's new this month:


- PGI announced the Dervish, and we've made our review/theorycraft for it.
- Annihilator now has a build guide and has been ranked on the tier lists.
- Hunchback IIC now has a build guide and has been ranked on the tier lists.
- The Build Guides have been improved - more information, prettier layout.
- Minor ongoing updates to builds and tier list sorting. We'll begin posting more detailed changelogs once things have settled.

Beta launch has arrived!

Submitted 1 February 2019 by Tarogato

It's been over a year in the making, but we're ready to get this party started!


This is a beta launch, which means things could change somewhat drastically, such as site aesthetics, and tier list philosophy. Visit our Discord and join in on the discussion. Content is slim on launch, and that's for a reason - I expect to get bogged down with feedback. We have a bunch of build guides ready to go, pending approval, so there should be a constant stream of content being injected. Check this space for updates!

While I did most of the site design myself, Scuro did the real hard work of translating my needs and wants into all the backend code and database integration that powers this site. GrimMechs also wouldn't be possible if it weren't for the Community Contributors that I recruited to populate our build database and tier lists. Ensuring that builds and tier list placements are agreed on by a majority of Contributors is a lot of work, and I selected high-tier players from a broad range of competitive units to foster diversity and ... intense discussion.


This initial launch includes...


- Marauder IIC build guide
- Warhammer build guide
- Roughneck build guide
- Vapor Eagle build guide
- General Tier List, top two tiers complete
- Specialists Tier List, top two tiers complete


Coming soon!


- Skill Tree Guide
- Annihilator
- Mad Cat Mk II
- Cyclops
- Black Knight
- Bushwacker
- Hunchback IIC
- Hunchback
- Vulcan
- Wolfhound
- Firestarter
- Commando
- February mechpack theorycraft
