Hey There! Was fighting the first boss of ahn’qiraj for transmorg and it did something and now my sinister strike awards 0 combot points.
I’ve tried relogging, respecing, restarting the game, EVERYTHING!
PLEASE HELP IM RAIDING IN 5 HOURS AND I CANT DO ANY DAMAGE
Yeah the first AQ boss has been bugged since Wrath released and they’ve still not bothered to fix it.
It can de-activate talents, render spells useless like SS giving 0 combo points etc.
Not just rogues affected by this either.
I am not 100% sure, but if you “unlearn” your talents to reset them, that might work.
Sad to see it’s still buggy after all this time tho.
Wait you actually have to unlearn the talents now? 
In WOTLK a simple talent swap if you had dual spec worked fine.
