Healing RP is suuuuper fun. Since there's nothing here, I'll write up how I've healed on different characters/classes!
Lunathorn is a new character that I have never RPed as and am not likely to RP as any time soon, however, my perspective on her healing magic is that she'd be very Traditional, require reagents, and follow rote and ritual. I doubt she'd be the sort of character who would rush to help someone bleeding out on the Cathedral steps, because the kind of healer I would RP her as is more methodical and slow - she's not a combat healer, she'd be more the person who spends hours working ritual, magic, and physical therapy to heal a long-term injury. And, naturally, plenty of herbs and balms and teas and meditation, with a miiild bit of xenophobia - why would she spend the gifts Cenarius on a race whose lives are so short and constantly being wasted? She'd much rather expend her energy on someone whose lifespan is likely to last 100+ years.
Keates is a new-ish character, I've had her for six months, and she's actually not a paladin like her class says - she's a priestess drop-out, because SHE'S NOT A PART OF YOUR SYSTEM, MAANNNN. That being said, she's a lot less interesting to roleplay healing as, it's the standard wooshy Light noises and warm sensations and Holy energy spilling from her palms, etc. I do include some ritual, such as her usage of candles, and her (probably non-canon *cough*) use of diagnostic imaging in that she stuffs some Light inside you to do recon - she uses the Light to tell her what's wrong and where. OH! She also uses the Light to purify all surgical instruments, so that's kind of fun? Nothing like digging a bullet out of some schmuck with Light-imbued forceps.
Ashtivar was my worgen druid, before I killed her off and she became Lunathorn. Ashtivar was, by far, the most fun I've ever had roleplaying healing magic. Ashtivar was a Harvest Witch along tradition lines, or - well - my headcanon of traditional? She communed with plants, and when she healed, she would essentially pull a seed out of a satchel she had on her at all times, and tuck it in the injury - then I'd RP her as GROWING A MOTHERFUCKIN' PLANT inside of someone, or on the surface of the injury, etc. Different plants for different things; burns/surface injuries? Moss, lichen, something without deep roots. A severe gut wound? An oak tree. HAVE A SAPLING IN YOUR INNARDS.
Once the plant was grown, she would then -kill it-, and the energy that inhabited it would sink into the person's body and knit the injury; I RPed that this left an after image, a scar, a tattoo - permanent or not, up to the player's discretion - of the plant that did the mending.
Ashtivar was a happy-go-lucky shithead with a hazy relationship with the truth, a propensity toward immaturity, dick jokes, and heckling -- but she instantly became serious as the grave when it came to being asked to heal. If the injury was only superficial, or inflicted foolishly, she wouldn't do it; she'd become very offended to be asked to grow life, then quench it, for anything less than true need.
... and then my ACTUAL paladin, Dyna? She sucked at healing. Like, I'd /roll and it was usually a 50/50 chance as to whether she helped the problem or did more harm with her attempts at using the Light to mend. Too much Ret in her Holy. Even if it didn't do harm, it would usually feel like you were being burned alive, and even if it fixed the problem, she'd usually leave really messy, gross heaps of scar tissue due to 'sucking at healing'. (It's funny because she was my raid main through Wrath, as a Holy paladin, PVE-wise)
She eventually picked up plantlore from a druid, and went to non-magical healing methods when asked to assist, if possible. She's quicker to offer a poultice than to try to channel the Light.
I like this blue but can we consider purple :^)
