I've been going through all the swag I picked up over the year of VIP daily gold roles(after canceling VIP because SSG can't come up with decent benefits). I picked up about 15 different cosmetic armors in total... not one of which can be worn by warforged. Thats 15 different ones, not counting the large number of duplicates. I'm not sure there's a single warforged-friendly cosmetic on the entire gold role loot table.
