There's not enough gods, and they cost a small fortune to unlock for use, and there's no real sense of balancing(How is Ra in any way viable compared to He Bo or Zeus?), and you can't even queue up with 4 people since it forces you into either 3 or 5.
Still, the game can be a lot of fun. I just hope they fix the problems they have so far, since the first person all skillshot setup is really neat.
