Since the current PTS changes are making siege stackable and unifying repair kits, I think it would be a good time to add a dedicated pvp quickslot wheel for siege and repair kits as well. I know that I personally have around half of my wheel dedicated to different kinds of potions so it can be a hassle being forced to leave combat before being slotting what I want. Unifying repair kits will help with the wheel clutter, but there are still many different kinds of siege to be slotted. This is doubly so since I expect to actually carry more different kinds of siege now that they stack.
