I come from Aerenal.
Never really heard,
"We can't do that.."
this much there.
Hear it alot on Sarlona.
I think its cause on Aerenal we had a serious lack of clerics so we were forced to do quests different ways.
Also the mass exodus at the first sign of trouble is comical. I always found the best way to fix a problem is leave and find another group to help me through.
