Well, some people roll need on gear simply because they want the piece for glamour, or wants to trade it in for gc seals. Imagine being forced to greed on something you really want for glamour and losing the roll every time. Usually, if someone requests a piece of gear, I'll pass on it and let them have it (unless I really want it for glamour and have been trying to get it forever, haha). If nobody says anything, then it's fair game.
