Vol'Jin by SirAndy

My brother said "Do a Troll hero", so here we go with Vol'jin, the leader of the Darkspear tribe and your new Warchief! Vol'jin's kit is a mix of the Warcraft 3 Shadow Hunter's, his abilities as a faction boss in World of Warcraft and even the ability of his Hearthstone card.

Description:

"Destroys enemies and structures with various magic. Regenerates health and mana much faster after taking damage."

Vol'jin is a Ranged Specialist who sacrifices the Hero damage capabilities of other Specialists (like Zagara and Nazeebo) for devastating siege potential. His trait Troll Regeneration rewards Vol'jin's presence in a team fight, in lane or in the capture of mercenary camps. In contrast to Muradin or Morales, who regenerate health after avoiding damage, Vol'jin draws on the otherworldly regenerative capabilities of trolls to keep him alive in the thick of battle. His first ability is Shadow Word: Pain, a Shadow Priest staple. Shadow Word: Pain is a damage over time effect Vol'jin can place on enemy Heroes, minions or mercenaries. The damage is modest, but a target who dies while affected by Shadow World: Pain will reset its cooldown. This makes it a potent means of clearing minion waves. His second ability Hex will Polymorph a target, preventing them from casting any spells. Unlike Brightwing's ability, targets hit with Hex move faster and the duration is shorter. As such, Hex is meant more to scare off a target than to focus your team's gaze on. His final ability is Serpent Ward. A totem that deals damage, Serpent Ward sees the greatest use against Towers and Forts. It deals twice as much damage and left unopposed, Vol'jin can quickly wipe out undefended Structures.

Vol'jin can spec to improve his team fighting prowess, increasing the damage dealt by his Shadow Word: Pain and by selecting the Restless Spirits heroic. He can also choose to make his siege damage even more potent, through the use of the Shadow Word: Death heroic and making Serpent Ward into a devastating siege mechanic.
