What a bunch of crap man. Imagine you have a skill that can bust immunities. Do not want to use it? Use a weapon that spawned with reduce enemy resistances. Is your build based around a particular legendary weapon that doesn’t have that stat? Well there is a legendary amulet that grants an aura that reduces resistances. Don’t want to sacrifice the large amount of (crit dmg/cast speed whatever) that can come on a rare amulet? There are other types of damage you can incorporate, there could be thrown items, there could be consumables, there could be crushing blow and culling strike… use your imagination.
