i posted this a while back but it sorta got lost in the flames.. i thought it was a good idea anyway, or at least worthy of discussion so here goes, blatent repost.
"you know that new earring that had "potency of cure effect RECIEVED +5%"? lets make that a spell! give it a strong duration, single targetable, and HEAVILY influenced by enhancing magic skill (this way if they decide to give it to whm later we may still have the "better" version) you put it on your tank, and huzzah!
then in a bigger group situation, this is still helpful even if you have a whm. you're helping him cure more efficiently. this also mitigates the issue of being as overpowered as giving rdm cure5 proper because you can't cast these bigger cures freely, you have to setup and "predict" who is going to be taking the damage. and if you end up "needing" it on 4-5 melees.. well.. then you get a whm?"
sorry for the obvious copy/paste, but yah.. people have been wanting something to improve rdm as a healer. a lot are screaming for cure5.. and a lot of others are screaming no, because of the old issue of "replacing" whm. well.. that's my idea. so long as it's kept separate from the current cure potency cap i see a lot of potential in it.
