The higher your level goes, their default weapon upgrades and their default outfit get replaced with different looking outfits, maybe they just have more armor on them or something. You know how Diablo 3 followers change appearance as you progress in levels? Same thing. This would be dope. I'm just too lazy to constantly find new armor for my companions, and I like their original aesthetics when we find them. Piper's trenchcoat is too cool for her to give it up for some dingy armor. Nick can't even wear armor. MacCready's Duster looks dilapidated as hell. But can Piper really make it through the Commonwealth with the Sole Survivor with a measly 10mm pistol? Shouldn't she upgrade to something much more hard hitting when you've leveled up significantly? Just an idea. I know most people out there probably outfit their companions on their own. But I think a default progression system would be cool too.
