Haven't seen anyone talk about this but we almost have relic loadouts. No idea when this was implemented, but I think this is new because I remember checking out the Smart Equip stuff a few patches back and it was pretty close to worthless.
In the Smart Equip you can now Pin every single slot in your 'Custom Plan' loadout and that's something you'll always be able to go back to on that character. The big downside is that you can only save one set per character, but at least it's something.
