Hi i know its not even a problem but when you playing older contents like first DLCs or even vanilla game you can encounter some NPCs wearing some random or unfit outfit styles. For example there are couple of Aurorans in Fighters Guild Questline wearing Golden Saint outfit although there is updated Aurorans using Meridian Style comes with Wrathstone DLC. Or there are some Silver Dawn members in Orsinium wearing some random style like Orc. These can easily replace with updated motifs because these motifs already in game. Im not saying that after every update they should update every NPC's outfit but its coming to new gen consoles. Maybe with that update they should overhaul the game and the older content so it doesn't look outdated. Im leaving some in game screenshots for examples. Like i say its not a big problem but when you playing older contents game looks so dull. Even the key NPCs looks so unimportant.
Dirdre, a Silver Dawn Member, can be found in Orsinium DLC using Orc Style
New Silver Dawn style came with Wolfhunter DLC
An Auroran Battlemage can be found in Proving the Deed quest using Golden Saint Outfit
An Auroran in Depths of Malatar Dungeon came with Wrathstone DLC using new Meridan style.
Or atleast they can overhaul key NPCs like Neravar in Clockwork City DLC because he looks so dull unlike Tribunal. He doesnt even have his signature sword Truefalme but the model is already in game.
