A wider range of minigames should be better cause no offence kChamp, pongshock is a bit boring. And when you play minigames i would be cool if you could win tankcoins or extra xp during minigames.
On deathmatch you should be able to have like 1000 health since with 300 health lvl 50 deluxes just kill me in 5 rounds before i can do any real damage and get any xp :(
You should not have to pay either to make your own custom maps. There should also be a way other than collecting slowly from boxes or buying tank coins. Example : minigames, as a win bonus, daily suprise and other ways like that.
The host should be able to kick people during the game. For example your in a stack and someone is not stacking you just kick the person instead of shouting tons of insults at him/her.
