Hi there, welcome back!
I've not played since Brawler/Incinerator were new Mechs, so I assume a lot has transpired since then.)
I have the feeling that Brawler is one of the very early mechs available on the game, whereas incinerator has been added way after (2014)...
Regardless, things have been quite complicated for Hawken. The economical model didn't work and the original developers and owners eventually bankrupted in July 2014, without noticing the community. During the Great Silence, the forum closed and some servers went bad... The game has been rebought on March 2015 by Reloaded Games, which has worked since then on server enhancements and development setup for future updates. Keep in mind however there has been no update for more than one year. But the new dev team publishes update articles quite frequently. The latest one states about the hiring a new developer and other good news :) .
But well, despite of that, the community is still there, up and running. So, welcome back, just grab a mech and enter the battlefield!
