All Im saying is that instead of having 1 "active" gear sheet, which you currently have your gear in (not in your inventory), you have 2 "active" gear sheets. Then you can place one set in one slot, free of your inventory, and a 2nd set in the 2nd slot, also free of your inventory. You wanna do some PvP, click on the 2nd active slot. This is purely for changing your gear quickly from PVE to PVP for the expertise.
