Seems like you already have an answer to your problem.only worlds without rivalry are able to kill these bosses
Rivalry isn't the problem, imo. We managed to kill mordy with tons of griefing for over a year. There hasn't been any mordy griefing since the new engine, yet we still fail with the right amount of numbers. Anyway that isn't the point. A clan merge or working together won't fix the MAIN issue here, which is lag and targetting issues. Only OtM can fix this. I shouldn't have to waste several seconds of Lix running around trying to click on Mordris/druid because of a targetting issue. My spite sometimes glicthes when trying to cast, because now I have to be much closer to the target to use. There's several factors here thats making Mordris harder for us and even if we all decided to kill together, yes we may down her, but the bugs will still be there until otm fixes them. But at least i can play....several clannies can't even log anymore because of the lag.
