In 3e, bards can heal. Either you come up with some very compelling backstory for bardic magic, or arcane healing is not that hard.
*3E design brainstorming*
"Hey Bob, what do we have for Bards so far?"
"Well they have almost as many skills as Rogues, they buff their allies, and they have some wizard spells."
"Hmm, they still seem like they suck"
"What if we gave them some healing magic?"
"Aren't they arcane?"
"Yeah, but isn't that better?"
"Well they still suck, but I guess they suck less with a bit of healing thrown in"
