Wands are actually a godsend. Bard, Ranger, and Paladin with one wand replaces the heal bot entirely so that no player has to exclusively devote themselves to the role outside of just carrying a replaceable wand. For the price of one wand of Cure Light Wounds, you get 50d8+50 points of healing over its 50 charges. For a comparable price, you can get healing belts from the MIC that can heal up to 6d8 of damage over 3 charges that replenish daily if your party has no class with Cure on their spell list and none of them have any UMD ranks, or don't like the idea of wands in general.
