Improving my DPS as Fury

[flint salmon]

Hello, I'm back to WoW after a break, and I joined a very nice guild and we're progging through LoU.
My issue rn is that I feel, and from what I've reserched I am, underperfoming, and I can't figure out exacly what I'm doing wrong. (a lot I suppose)

I use Luxthos WA and my only macro that isnt [@cursor] is:
#showtooltip
/cast Recklessness
/cast Avatar
/use Tempered Potion
/use 14
Where 14 is my House of Cards
As of today I've been in several prog fights but few actual kills, it is also my first time asking for help in this way so if I left out any important piece of info please lmk.
I hope one of you might show me the light.
Much thank you!

Hey, from a short look through your last cauldron log it seems like you're delaying your bladestorm on pull for some reason, cast it after your first rampage or after roar but you have to use it early so you can get it as soon as possible through anger management and marked for execution.

It seems you're executing a lot, remember that you only use it generally in any of these cases:

• juggernaut is falling
• 3 marked for exec
• 2 stacks of sudden death
• sudden death running out
  I recommend using the execute weakaura
