Don't know if I agree with that. There is obviously infinite more time to react to elemental damage in a turn-based setting versus real-time (unless you're a world object.. which seems to strangely burn in real-time regardless of being in the middle of a turn-based encounter). And once the element is properly removed it isn't a danger in the subsequent turn.
It's not about reaction time. It's about damage. Fix the damage, and you don't need to do any other fixes taking into account real-time or turn-based.
