Not sure Paladin completely sums it up. I'm a combat medic, I tend to play classes that can heal team mates, but mainly I like to be self-sufficient and able to heal myself. If I can do this entirely freeform, I'd probably be a longbow type as well, but if I'm only going to do glancing shots I'd go for a two-hander melee and have some actual power. I'm also an atheist and I don't appreciate being associated with holiness.
So...a regenerating berserker who occasionally heals his allies. Which is ridiculous, so paladin it is.
For the record, in RPGs I generally am just a barbarian, but with a twist, whatever that may be. In Skyrim for example it was self-healing and enchanting, which come to think of it, is pretty close to what I described above.
