Another option is to just stack regeneration stuff. It literally does not matter if you specced into heavy armor or not, just wear it for the enhance.

Regen isn't very effective against sword arts.. it only acts against the attack as a whole.

Correct, but what is the alternative? Mitigation does not exist, so indirect mitigation (as in healing to offset the damage) seems pretty ideal to me.
