There are 2-3 things I would like to see added:
Ability to kill other player based on total damage given. It would have to be calculated at perhaps 1000 points against in a 10 turn game (or 1500 with 2v2, 2000 with 3v3) that way you would be rewarded with early win if you really dominated another tank
Additional weapons at a hire lvl. Say maybe a Rail Gun that would shoot through walls and multiple players. Kind of like an unstoppable sniper
