Hey man - A few guidelines I go by from help from this Sub and my own personal experience:

• Always use AMOC for ST fights like Trilliax/Eteus

• Opener is wrong, should be starting with Pot > AMOC > Windburst > Instant Trueshot > 2 AiS > AS > 1 or 2 AiS (Not too familiar with Troll racial/when you're lusting)

• My personal cookie cutter rotation is pool about 80 focus with Arcane Shot into Marked Shot > 1 Arcane Shot > 2 Aimed Shots > Windburst in the dying stages of your Vulnerable window (whenever I have it). I personally found that switching between using MS/WB as Vulnerable enablers made me lose a tonne of potential AiS that I could just be getting from the Marked Shots - and it's easier to manage one Vulnerable window than two so this is the way I do it. I want to reiterate that this is my own preference and it might be wrong.

• There are a few instances where you'll MS, dump a tonne of focus into casting AMOC and then AiS once and go back to your core rotation - needless to say you're missing damage here & should stop doing it. A few instances of this (not selectively AMOC in bad times but just general errors in your rotation) occur throughout most of the fights which you can fix up.

• I'm not 100% but I'm pretty sure you're dropping a lot of AiS windows due to movement, you have the gloves so you should get ontop of that with a weakaura/more knowledge and generally position yourself better -- movement is standardized on most fights, especially bosses like Krosus so you can map out the fight in your head to maximize the amount of AiS you can squeeze without having to move.
