I've got a lot of experience of boosting thru SM Cath with my LVL 80 Hunter, and i have to say its one of the easiest class i've ever boosted with. My Plan is too basically; Buff myself with Aspect of the Dragonhawk, eye of the beast with my pet and run and pull the first courtyard back to me, i then drop an explosion trap, i then volley them down. Then repeat with the second courtyard. Next open the doors to the Keep part, then instead of eye of the beasting, i attack just Mograine and he shouts something like "Infidels get them" and the whole of the keep pulls onto my pet. then i switch the pet onto passive and click the pet follow button, drop another Explosion trap and volley them down takes me about 15mins a run!
Easy
Thanks
