Is that a corver or somin new? Cos it sounds alot like somin ive herd before.
Also you coverd some of the player vs player its all arena bassed arena usally shows people who are amazing and who face roll in one or two matches. This type of setup has a lot of pushing towards mix and matching heros for the best build and throwing around heros to counterstrike the others curent hero.
Power builds might not ever be a factor one could drop a "green hero" and another could drop a "red hero" and the red nerdplows him gameover. So it will see the players reaction to the situation and capitalising and having imense PvP matches!
This does seem if they hit it right to have some big old competetive matches that are uber great to watch!
(For nerd terms look above)
