They weren't the only ones to change, and for the worse either. For me, it is the Preceptor's Gear, which I really liked, and spent a fair bit trying to get. It looked fantastic, had no hood, and was the first set of robes I actually liked.
NOW, I log in to find that the robe has a hood, the robes themselves don't drape properly, the lower robe's *** sticks through the back of the upper, and it's got insanely stupid shoulder pauldrons of some type??
This is the stupidest looking bit of gear now, and I never would have wasted my cartel coins on this.
