If you want your runs to go smoothly, and without conflict, please avoid choosing Holohoax from the guild Simplicite on the Alliance side as a healer.
Numerous encounters with him, none have turned out positively. Insults and raging are his specialty, as is running out of mana in less than 30 seconds flat. Often causes the group to scapegoat and turn on you, or whoever else they deem worthy of their vitriol.
