It has the potential to be good. When playing PvP, where time is limited and you're at the mercy of the game to send waves of enemies, needs fixing. I will be sitting and waiting 5-10 seconds at a time between waves and sometimes between enemies. It makes the killing of enemies, the way you score points and hopefully more points than the other PvP player, redundant. It is extremely frustrating when trying to rise through the ranks when the game has this glitch that makes it impossible.
