I doubt it. Most solo duties are capped at, or just a level or two above the quest level, and even then I don't think gear affects RP duties in the first place.

If AoEs are spawning that fast you're either supposed to keep moving to dodge them all in quick succession, or you missed some other telegraph. Nothing with a marker is completely unavoidable (and you have defensives and heals for the truly unavoidable damage).
