I thinks it would be a good idea to have kill counters in blockwars and eggwars and other games of the fighting genre. It would help as you could set yourself a target or compete with friends.
THAT, or you're too lazy to do math to find out how many kills you got. It's just more convenient to have it count it for you every game.Normally I would just say that this is just useless since you could just check your stats before going into a game and then compare with the new stats after a game. This can be a bit tedious to do for people who doesn't know (Who doesn't know how to subtract? :p). You have my support on this one! :D
