Used to play MWO for a long time, but once they released the skill trees, I just stopped logging in. Having to do the skill tree for every.single.mech I owned/wanted to play, just seemed like too much work for a game I was slowly losing interest in. Looks like they have added a lot since then, though.
Brawler mech looks like it'll be great in this. One of the issues with the streamers I've seen is no one has really taken advantage of min/maxing armor. In fact most run around at 1/2 armor or so for most of their play time, and then wonder why enemy versions of the mechs they are playing are tougher... But AC20s are brutal, multiple SRM6's are just downright scary. Toss in a few machine guns/small lasers, and add in some special +melee items (I have seen them drop in videos) and that's one mech you do NOT want getting close to you. Certainly a mech I'd like to build.
