Not sure of your rotation and in-between trinkets and other misc. dps. Im 402. Twice this week (july/2019). Group listed all item levels and I was last every time. Others 416 to 432. Both times I was told if im low dps Ill be kicked. And both times I was first dps @ 32k. Of course no one says gj but there fast to threaten. This is why I dont raid any longer. And yes all the fast judges I know the others just sucked. I dont say that usually about gamers but they deserved it since the threat.
Anyway, As for you…Yes learn the pro rotation from all the tubers and other sites but dont turn into robot mode and expect every thing to fall together. I only use X-roll add on (thats it). Everything else is by feel. If my RTB suxs I will re-roll at 3-4 combo. I will also dispatch on 4 so I dont waste a combo. Other lil tricks is when exactly to hit blade flurry. Thats a huge dps boost when dont correctly.
Lastly, I am assassin but once again I cant get any friggen daggers to drop. Daggers dont work in main hand for outlaw. I cant fathom why but it just dont. Stuck playing outlaw since start of bfa. Back to my main reason playing games…Its for fun. This hasnt been much fun not able to play spec I want. Enjoy Kay
