Heroes of the Storm Announced Diablo Block

Blizzard Entertainment's Free-to-play MOBA, Heroes of the Storm, has announced that they will soon be launching a block of Diablo themed content that will add a new map called "Eternal Conflict" as well as new Diablo characters.  The map features a battle into Diablo's High Heavens, where Diablo's power has corrupted half of the map.   Players will also be able to fight on the side of good or evil at the center of the map in which two immortals are locked in an eternal battle.  When one falls, the victorious side will reap the rewards as their immortal leads the march towards the enemy base.
