[MENTION=9249]Viktyr Korimir[/MENTION], would it be safe to assume you are unaware of the fact that divine casters do not have to prepare all of their spells at the same time? A healer isn't forced to guess which spells she needs ahead of time. She can save as many of her spell slots as she wants and prepare them later, as needed. A cleric has to guess in the exact same way regarding removal of status effects. It has been my experience that for such things, casters often leave a spell slot or two open to deal with such things. Your whole argument then boils down to the fact that you think spontaneous healing makes clerics better. But spontaneous healing is just a convenience. It is by no means necessary or even that incredible. Maybe you didn't play AD&D, but clerics got by just fine without it back then. All you need to do is keep a few cure spells prepared to deal with emergency healing in combats. And for emergency healing in combats, healers do it better. Outside of combat, it doesn't matter. Most clerics I've seen just use wands of cure light wounds (or lesser vigor if its allowed) for outside-of-combat healing. Healers can do that just as well as clerics can and their cure spells pack more punch and some are even available at an earlier level than the cleric. Your argument doesn't hold water.
Do I even need to mention scrolls?
