When is this game gonna have that? There is none of it.
There are couple types of balance and one is that the game is 4vs6 and the game thinks it's fine, it's not like I can force one of them to move to the other team and teams would be balanced in numbers.
And no any "skill" balance either, other team is killing other one alive so of course that is fine, just accept your fate and wait for maybe you get luckier with better composition of players next time. These flaws are fixed in nowdays FPS games, but not in this.
Hastly written so it is not English at best, but you get the point.
