Ive never seen a post backed up by numbers in a simulcraft chart that shows discharge used on CD doing less dps than not using it on CD....could you link that info please?
Edit: I researched and looked everywhere I could, and there is only one guide for Deception Assassins out there with absolutely no one doing viable testing on it. In fact the one guide that's out there is one that is filled with old builds and outdated information. I would think there needs to be some more research done into it.
In fact, in the one guide he states it takes him 2 cycles to get to 5 charges. All I can say is that is one awfully long rotation he is using. I can get to 3 static charges in one rotation. So waiting for 5 on a completely static non-moving boss is easily doable and I will do some testing to see how it affects my dps to wait or to use it on every CD.
I can guarantee you though that holding onto a full static charge is a dps loss.
