Valve and Riot just collectively shat their pants.
Blizzard has finally announced the formerly named "Blizzard DOTA" and "Blizzard All-Stars", originally an SC2 map
To finally have its own game, similar to Dota 2 or League of Legends. A new MOBA with Blizzard characters, basically.
Namely Warcraft, Starcraft and Diablo. It's called Heroes of the Storm. Y'know... "Storm" as in "Blizzard"

Although it's pretty retarded, now that Blizzard has two games with the same acronym of "HotS"
The other being Starcraft II: Heart of the Swarm
