This is one of the best designed maps in any game that I have played.
I am sort of getting tired of co-op vs AI though. Its just becoming way to predictable. I think its good for getting use to a Hero and trying out new things.
I think its time for me to start doing some pvp matches with Grux and maybe Sparrow to increase the challenge and get less bored with it. I have Grux figured out so well in the AI matches and that one pvp match was awesome.
