Vol'jin by Crackjack

The shadow hunter Vol'jin, son of Sen'jin, chieftain of the Darkspear tribe, and rightful ruler of the Echo Isles, was a staunch ally of former Warchief Thrall. After the Echo Isles were conquered by the traitorous sorcerer Zalazane, he resided in Orgrimmar at the side of the Warchief, later fighting alongside him during the Battle for the Undercity. After years of exile, Vol'jin led an attack against the Echo Isles to end Zalazane's evil rule and retake the lands that Thrall had promised them.

Following Garrosh's defeat in the end of Mists of Pandaria, at Thrall's insistence, he assumed the role of Warchief of The Horde, the first non-Orc to do so.

During the attack on the Broken Shore he was pierced in the abdomen by a fel spear. Badly injured, he was taken back to Orgrimmar where he communed with the Loa who gave him a name, and as he drew his last breath in Grommash Hold, he named the new Warchief: Sylvanas Windrunner.
Vol'jin is a ranged Multiclass hero
At the start of the game he has to choose between Blessed or Voodoo
Blessed will allow him to make use of his supportive spells while all his aggressive spells will be locked
Voodoo will allow him to make use of his aggressive spells while all his supportive spells will be locked
Once Vol'jin chooses between either Blessed or Voodoo, he will then be bound to that choice for the rest of the game

Supportive spells: Healing Stream, Hex, Protective Ward, Big Bad Voodoo and Serendipity
Aggressive spells: Glaive Toss, Shadow Shock, Serpent Ward, Shadow Barrage and Shadowcall

Vol'jin won't be granted both heroic abilities in either stances
