I just put none ex/rare ammo for TP/WS set, and added a /wait 1 /equip ammo none ex/rare ammo right after QD macro.

So everytime when I fire off QD it should swap back, if it doesn't then I can click WS/TP macro to swap the ammo back. Everytime when I do an event I just make sure I have 1 full stack of none ex/rare ammo so I don't run out, if I do /ra events I make sure I have 2 stacks.
