Help me get out of grey parse! (Fury)

[pale canyon]

Hey all,

Swapped to Fury this season and I could use a hand. I'm mostly fine in M+ but in raid I am absolute garbage. We are still progging heroic, but man I am just doing like 4% parses out here and would like to feel like I contribute a little bit at least, so any help would be appreciated.

I am Skragg. I don't know what can be gleamed from here, but I think I'm hitting the right buttons but maybe not doing them at the right time?

Too many bloodthirst, Use Raging blow until no more charges or rage cap (avoid wasting rage) or you re about to lose enrage, then rampage, and resume. Execute when the WA tells you to making sure to waste no cdr on bladestorm, (if bladestorm is up and 3 sacks of in for the kill) bladestorm first. Soulhunter is odd to judge cuz i didn t check if the tanks even tank it right, but for forgeweaver you wanna make sure to have a bladestorm for ideally every add set and cleave them down. That should do it. Don t sweat the paddy fights like soulbinder or Araz. Get the Single Target ones down first.

Should I only use Blood Thirst when it's super high crit and I need rage or to heal?
