Clan stacking and otherwise imbalanced games are a problem
Servers really need to start trying out some kind of balancing mechanics. Even very rudimentary shuffling of teams based on players' win rates would lead to fewer brutally one-sided games.
And servers really need to start banning clan stacking. It's an absolutely terrible thing for this game. No one who cares even slightly about winning enjoys having zero chance to win when a bunch of clans get together to stack one side to roflstomp their opponents in every game.
I lose all motivation to even try to play when half the team dies in the opening minutes, loses their vehicles and when I look at the score screen, a third of the enemy team is made of a few clans playing it together.
