I'm in Act III, and there are a couple of quests/tasks that I just don't want to do. Am I the only one? 1. "A Servant of Death." Berath wants me to kill the oooooold druids. But the only way I see to kill the Archdruid Rehstin is to kill the entire Ethik Nol. Nope. 2. "Sacrificial Bloodlines." I'm not getting involved in this family mess. No way. Are there other quests that people refuse to do?
