I constantly get paired with opponents with twice my crit in pvp and half my crit in coop. The lag is so bad it is unplayable about 25% of the games. Especially if you are up against a Shaman deck. I merge or swap to avoid and all I get is a swirling whirlpool and my guy is downgraded or destroyed anyway. When you spend money you almost always get the minimum possible rewards. I will never spend another dime on this game.
