Help Improving and understanding why my average cast damage is so low compared to other arms warrior

[elfin hull]

Hey was hoping someone could help me understand why my average Ability cast damage is lower compared to similar i level arms warriors. I was wondering how i could increase these numbers or why its so low. Any advice on increasing dps or places to improve would be greatly appreciated. Thanks

From what I see not enough rend using

Your execute seems a bit low as well

Thank you

dont think about "average cast damage". Just dont man. Instead - think about the actual tangible things you can work on.
How good is your opener?
How good is your rotation?
How good is your juggmaxxing?
How good is your cooldown management? Are you aligning your cooldowns with the mechanical breakdown phase of Vexie?

I took one quick look and i saw some quick things

You're not clicking execute properly while in execute range. Why are you clicking slam in execute range?
You aren't playing around Opportunist at all
You aren't playing around Juggernaut at all
You aren't playing around Marked for Execution at all OR not as well as you're supposed to
You're not using a tempered potion

If you have the time could you elaborate on these please. Currently in execute phase i just spam execute 2 or 3 times then MS and use opportunist for rage management. Appreciate your input 🙂

check out the wowhead guide for the Execute Phase, it answers all of this:

In execute, your proirity should be:
MS (if you have 2x EP) > Opportunist > Execute > Overpower
