Since the Koenig and Ares (Wootz) sets were added, how about adding some of the NPC exclusive armor sets from XI that would fit in XIV?
This one for example

It would fit well coming from Ishgard since it's from San d'Oria (Elvaan/Elezen nation in XI)
There are a lot of nice looking sets to draw inspiration from (or just implement) just like what was done with the Valerian sets. I suggested this one in particular because it's not bulky and won't clip as much (and I'm really tired of super bulky arms and shoulders on tank)
This is what it looks like in-game
