Hey man, sorry to hear you're having fury issues, without the ring you're going to have to rely on RNG like Zylo said.
One thing to point out, it looks like you're wasting a global cooldown on FOTI, whereas you could easily have put this into the combo rotation of your nem / CB. Whilst using felblade is a good shout, using it AFTER meta is less productive than using it before you go ham.
For example, when I open, I pop meta on boss, fellblade, Macro for Nem / CB / FOTI, then blade dance / anni as much as possible, if I see my fury dropping too low, I'll pray for a felblade proc.
I've got a video of arcway, skip to the bosses and you can see what I mean?
