Your favorite non-final boss in warcraft as new hero.

Recently, I read a lot of "booooone stoooorm" so I started to think, which "normal" boss can be a new and cool hero of the storm.

Baron Geddon. A big and slow (like hammer) fire elemental burning everything in his path !

Twin Valkyr. Like Chogall, you need 2 players to play this double-hero, but each player plays his own body. One player can mark an enemy to improve his twin's damages.

Mimiron is a mythic boss, but I don't know about his possible gameplay.

Teron Gorefiend. First death knight.

Putricide. Let's play with poisons
