Well he had CCs last night in the forum of Leyn'a, but he aggro the the entire room before I had a chance to use them. The only person I've seen tick off that many NPC at once is Lynk either as Lynk or Priss. My plan was just to CCs one and let CrisG do all the killing, help him get a understand of what to do. Also figured my healer could heal him since he doesn't have one yet. However, my plan went out the window when he attacked while I was still recouping my force from the angry mobs we just killed.
Thanks Mitiades, I really have no clue what abilities the Guardian has, so any help is really appreciated. I also have no clue why anyone would play one when the Shadow is soooooo much better.
