The long-running boffer LARP I'm in (over 20 years of a continuous world- I just retired a PC I had been playing for 15 years!) has that kind of richness and depth and complexity... and they have a self-selected "noncombatant" category that both PCs and NPCs can use. It's a really good idea to have something like that; it increases the diversity of players and the flexibility of writing and roleplaying.

It doesn't always mean that non-combatant PCs get stuck as healers. Rather the opposite... my aforementioned PC was one of the main (magical) healers in the game, but he was also a former member of the church militant and pretty combat effective. Weird, really. ;-)

Glad you're having fun! I can just see you with the sheet over your head...
