The game was good until a few months ago. But now, it is almost impossible to find a reasonably balanced match. Premium tanks/helis are too powerful. It only takes 2 of them to siege the opponent's spawn point and then there is no game any more.
'Pay to win' has killed the game.
Also, you begin to see players gathering on the strongest side, making it even stronger, and that is not balanced either by any 'joining' rule. Then the 'weak' opponents all leave and the match doesn't even start. Well done, players!
A few bugs have been sitting there forever and are never corrected. Lagging became more and more common during the last few months too, making 'footsoldier' matches almost unplayable.
