Allright so I was playing my rogue and decided to get a thrown wep so I could use Deadly throw , started fighting some mob , got 5 combo points, and used Deadly throw! then I noticed I still had the combo points so I used it again and again until I ran out of energy it was hitting for around 1k critting 2k without a cooldown I hope this is usefull to you rogues out there!
Edit: after further testing it does not seem to work on enemy players , but it did work on mobs.
