So we agree then, that Clerics excel in helping others become even more powerful( like Mages
), that his/her forte is not brute offensive, but passive offensive.
While you may think what Mage/Sorcerers can do is 'simplistic', do bear in mind that it does get the job done, and that is what matters.
Oh, and regarding parties, since you want to talk about it, ever consider that the rest of the party can just sit back, relax and sip some tea while the Mage/Sorcerer does all the dirty work? Sure, they can chip in now and then whenever there is Drow about, but a Mage/Sorcerer
is all about power, Clerics help add to that power.
