Ok, I threw you a curveball...
Why don't people understand the divine heal? Out of combat I rely on them to keep my mana high and keep the party healed. However, as soon as the first small heal in the heal over time hits, the player whips out a wand and zing zing zing healed to full.
Now I don't mind if you heal yourself, but don't invalidate my DH and then tell people I wasn't healing you. The weakest version of this enhancement can heal 15-45 hp. this is WAY better than a cure light, cure moderate, and compares favorably with a cure serious and you can get it much earlier.
Is it because we are expected to be mana batteries? Sorry but after I went into Deleran's with a wiz that was gushing about his leet new spell and proceeded to mana dump in the first corridor on trash mobs and then turn to me and say "got any DVs?"... I don't worry so much about DVs. My cleric is a heal/buff bot. I make sure my party stays alive and is protected. YOU watch your mana.
(btw, my answer to the leet spell slinging wiz looking for a mana battery?... "nope, I use them for healing.")
