The only other thing that bothers me, and still somehow continues to seem lore abiding and completely logical, is healing.
People RPing with extreme healing abilities that counteract nature itself, for instance, healing a wounded soldier who's arm has been cut off, replacing the lost limb. This goes past the pre-determined boundaries of healing that we've seen in game. I've witnessed roleplays where a player had instantly healed their own severed leg in the midst of battle.
When I RP healing, its not an easy thing and no way can severed limbs be 'regrown'. The way I see it, she has to concentrate on what shes doing and she has to know in exact detail what she is healing; its not just cast a simple spell and walk away oh hell no, she has to force the healing energy to repair the bone she just reset. She has had to master anatomy and physiology so she doesn't screw up. Its very exhausting thing to do, both mentally and physically as she is literally pouring mana/life energy into what she's doing.
In my mind, the healing spells also numb the pain as it works, so the patient doesn't feel their body being forced to repair itself at an insanely high speed which sound very painful.
My healer is also what we in RL would acknowledge as a paramedic/combat medic/ER doctor in the fact she is trained in more then just casting a couple spells when healing herself or others - she also can stitch them up, reset bones, make poultices, ect.
