Remove the ability for same AoE types to overlap. (ex, Fog Bank cannot overlap Fog Bank)
When an AoE of the same type overlaps, it'll reset its timer/duration (or the new tile replaces the old tile)

AoEs that currently heavily overlap (Star Rain, Final Toll, Magma Fist, Fog Bank) could get a tick damage increase to compensate for such a change.
Overall I think a change like this would make gameplay around such moves significantly more healthy.
