I have been told the Jester debuffs players, and thus is unwelcome in groups and raids. I have had a group saved by him when we had adds, and the cleric was oom and she cast the Jester and got filled with mana. Just curious, I solo with him sometimes, never got a debuff. I have never had him do anything bad to me, except the bread thing. He always seems to heal me or fill my mana. So what other bad things does he do?
