This post has been edited to include my ongoing steam review:
For me this game is amazing because I love the replaying the co-op campaign with different heroes. However, I would not bother buying it for the competitive mode.

[B]A list of issues:[/B]
There is way too much grind for a game with so little content because leveling up the heroes takes forever.
Both the heroes and the enemies can get stuck in the co-op campaign maps and this can be game breaking.
The heroes are extremely unbalanced and because of this the competitive mode seems to be broken.
It is difficult to get a full team because players disconnect and then the game never adds new players.
This game desperately needs more missions and maps.
