Actually, there is a big imbalance between the value of T6 mats which has to do with some having desirable stats and others not.
Currently, the farm for exotic gear is already a lot of work if you want multiple sets for build variety. Add in Ascended gear and even a single set is a HUGE grind. Currently crafting a single ascended back piece is equivalent in farm to 3 or 4 full exotic crafted set.
Implement a system like in GW1 where the armors are just skins and the stats themselves are cheap to get. Of course, it doesn’t mean getting some white armor skin and putting in it some exotic stats. Put some berserk insigna in an exotic armor and it gets exotic level berserk stats. The insigna itself can be a consumable and cheap to craft or some reusable item soul bound on use and a lot more expensive. People would still farm multiple armor sets for multiple looks or for easy switching in the middle of dungeons for example.
