Maybe they could put a natural "resistance" on player char's depending on level of char.. at level 1 your fire resistance naturally "not visible to player as in thier stats" but a invisible stat that would make fire seem to not hurt you as much and as you level up this invisible stat lowers so it "appears" fire is getting more dangerous at later levels but at the same time visible stat of resistance might be counteracting it... wow complicated balancing lol
