heroes of the storm could be fun from watching streams of it a bunch. we don't need to compare every moba game to lol and dota. moba is going to become an extremely broad term with tons of variations beyond typical classic dota setups (actually it already is, its just the other variations haven't hit it big yet). see the new magicka game, bloodline champions or whatever, etc.
though if people try to play hots super seriously as it is now I think thats a waste of time
also wtf at naming it HotS
thats got to be on purpose to game search engine results somehow involving Heart of the Swarm right? You don't accidentally make your two most recent game releases have the same acronym...
