I've messed around with the 36m , given it a fair chance, however it is not viable. Damage output is nice but the second anybody starts shooting at it the thing falls apart immediately. In my opinion It needs a health buff, or it's shield needs to reduce damage taken.
Now maps are nice, but we need some more for siege/Missile assault, I'm sure this would make many people happy if they were to just just implement some maps from other gamemodes into siege/ma.
Sorry for the bad grammar and whatnots
