I've started a cleric clanker for the reason I got tired of rude people on my mage and I wanted to decide who to help and who to say "gth..." (not necessarily just rude to me but in general or to other people)
I've been called a noob for trying to keep people alive instead of tanking everything
I do kind of feel bad when grinding with a cleric though
since I don't die and we just keep on grinding I burn SP really fast
thus I tend to abuse Life Tap...every 15 seconds until I'm back at 80%
I continue fighting while waiting for cooldown so it takes quite a few taps
so the cleric keeps on casting heal or regen on me
