If everyone is getting an AoE, I max melee range to only get hit by one. If it's only a few players with no additional mechanics tied to them, I do pretty much nothing about. It doesn't matter if I hit a player without an AoE or someone with an AoE hits me. The healers will do the same amount of AoE healing anyway, so there is no benefit in dodging as long as you don't overlap two or more.
