These are the PvE sets. They've said that PvE and PvP sets would have separate looks.
So it's alright for everyone sharing an armor class to look the same in PvE? It's a double standard that doesn't make most of us happy. Gear variety doesn't feel like it means much when it all looks the same. Uld has a lot of gear, so it's understandable that some of it shares models or are just recolors, but when the only unique loot comes from Algalon or the fact that it's the only loot of it's type, it just seems lazy.
