I would make it work properly in Win7. ;__;

If we're talking about gameplay-wise? I'd make headshots just a tiny bit more possible on any mech but the Jenner. Because I think I managed 1 headshot on a heavy mech in as long as I played the game.

And I'd probably nerf the flamer. It's a bit silly that a fast mech can run up to an assault, flame it to death, and boom! you have a brand new assault mech for salvage.
