Heroes of the Storm started life as Blizzard All-Stars before the name change around BlizzCon 2013.
There are many playable character from Blizzard titles such as Illidan, Lady Sylvanas Windrunner, the Diablo Witch Doctor, Murky the Murloc, Diablo, The Lich King and Kerrigan.
The MOBA is a “homage” of sorts to player created mods such as Defense of the Ancients and features both Blizzard heroes and villains in one big battle.
