Regarding your grim dawn complaint, did you not have enough level for augments? Augments and the crafted thingies you put on itels are what usually caps you until you reach suepr endgame in grim dawn. You don’t really need to be 100% capped anyway, I usually pick strong gear and augment/enchant it with resistances where I can to cap myself. The typical constellation paths also have resistances.

Dunno, I usually decide to lose that resistance and risk taking the damage and something else drops, it’s grim dawn, where most mobs die in 2 seconds and you can recover damage very fast.
