For the longest time I was against the idea, but now I agree with it. The cited reason for why they don't allow it is so players can recognise what armour other people are using in PvP. The thing is that, given the effectively infinite combinations of ornaments and shaders, you're never going to notice what someone has on mid-combat, outside of maybe a couple of Warlock chests. If they're using a Class Item, you don't know what perks they have on it just by looking at the player model. That said, I think Rime-Coat looks great, I don't know why so many people think it's ugly. It's nothing like the typical Warlock dresses that usually garner hatred and the moving eye is sick IMO.
