Arms warrior issue with dps

[Jablee 0]

Hey all
As the title says im having issues with low dps atm, when i sim myself on raidbots im supposed to do 1.3mil dps ish (iknow its perfect conditions) but atm im roughly doing hardly 1mil unless its execute phase. Any tips or suggestions i can do to improve my performence.

Here's a log for examination pretty much represent my overall performence for single target bosses: https://www.warcraftlogs.com/reports/TdhwyZKXq2rtjbxF/#fight=last&type=damage-done&source=14

Pretty late with this, but thought it was worth putting a few points:

• Your casts are really slow - as in, you take far too long to decide what to cast at certain points in the fight and then end up making the wrong decision. At around 50 seconds, you end up not casting Mortal Strike for nearly 10 seconds, instead choosing to cast 3 Whirlwinds. Check the priority in the guide, since the adds weren't up yet and you simply ignored the priority. This is fine when cleaving the adds once spawned, but not on ST.
• Why don't you use Heroic Leap more to drop decimates and to move from smash? It results in less downtime.
• Your Battle Cry usage was really poor. You completely missed a cast because of a massive delay between your first and second casts.

Just the things that were most noticeable in your log.
