So after Blizz nerfed assas and bufed sub all of a suden every rogue decided the best specs were combat and sub and kinda abandoned assas. I recently got my second heroic dagger and I decided I was gona do heroic Thok as assas cause it made sense after all the fight is heavilly movement based and assas poisons tick for way more than the other 2 specs, I wasnt realy expecting much gain but I was kinda amazed by my DPS.
I then decided to do heroic Paragons as assas as well, since thats also a heavilly movement based fight. It was my guilds first kill of H Paragons this week and my DPS was again insane (I had the bloodletter buf so its not a situation of gainning extra DPS from bufs). We proceeded to clear the place on normal and I went assas on Garrosh just to see how itd go on a non moving single target fight and again my DPS was superb, it actualy topped my sub DPS from the week before (granted that if I had tried sub again now that I have 2 daggers as oposed to 1 dagger and 1 slow weap I believe Id have done more damage than I did in assas).
Now this is not a player situation cause Im ranked on both Garrosh and heroic Thok on all 3 specs on the top 30, its just that assassination is actualy doing way more damage than ppl seen to think it is, I was actualy dealling more damage tham I simulate and its the only spec where this happens.
I think this is one of these cases were ppl just went with the flow and since everyone is going combat and sub nowadays they just abandoned assas.
