Okay, so in the recent past, we've heard all sorts of complaints about c/c's being stronger. Less equipment reliance, less gold dependence, etc. My suggestion to balance a little more, is a weakening or removal of healing items.
Off the top of my head, I can think of 4 items an neutral/evil can get: a scroll, a stave with 2 charges, and 2 eatables, all that do around 30-50 a pop. All these items are easily gotten. With a good, you can get all these, one of them requestable, plus another stave with a whole lot more charges, that is also requestable.
I think the problem lies in the fact that said c/c can be back into a fight much more quickly than a melee, because of their limited healing ability and the necessary sleeping time, compared to a c/c that can recite scroll/brandish enough to get their hp back up to get into the fight again.
I think this is also the reason why ogres are played so much. Basically, a non-ogre melee has to beat their opponent down enough to make them run or kill them. If they can't, they're on the run until they can berserk or sleep enough (if they aren't carrying eatables or have scroll/stave), to get up enough hp to get into the fight.
Perhaps having said healing items be more dangerous to get, or having them heal less would balance it, I'm unsure, but I think this is enough to get some of you thinking.
