I've found two bugs in EPL. The first: When burning Overstuffed Golem corpses in the quest 'Scourged Mass' (http://www.wowhead.com/quest=27528/scourged-mass), you set yourself afire with a debuff. It actually quite cool and 100% harmless in anyway.
The second: The follow-up quest 'The Corpsebeasts' is bugged. There are no cult members in the designed quest area, south of the questgiver 'Crusader Kevin Frost <Argent Crusade>' (http://www.wowhead.com/npc=45831/crusader-kevin-frost), that are channeling and there are no Corpsebeasts. The closest I've seen is 1 Corpsebeast laying on the ground but when I approached it the Corpsebeast corpse just disappeared. This is sad because I was seeing forward to get this quest reward for my Warlock 'Overload Robes '(http://www.wowhead.com/item=63015/overload-robes).
Your sincerely Sebastian
