I went back to your armory link to recheck your spec, as I couldn't remember it. Seems as though you've changed it...regardless...
Deep DestructionCoDoom > Corr > Immolate > Incinerate Spam/Chaos Bolt Spam
- refresh your DoTs when needed. depending on how deep into Destruction you are use Incinerate or Chaos Bolt. It wouldn't hurt to use both, if you think you can manage spicing up the rotation without much loss to DPS. CoDoom outperforms CoA in deep destruction because Molten Core was moved. Use Conflagrate whenever the CD is up, and throw a couple Soul Fires in there for shits and giggles.
If you decided to spec back into deep Destruction, I'd suggest checking out
this build. It scales very well with spell power and crit.
Glyphs are a major boost to your DPS. Always make sure to keep them updated, and prioritized. You should focus on
Immolate
Conflagrate
Incinerate
or Chaos Bolt // again depending how deep into Destruction you are.
As for your current spec, or as WoW Armory lists it, it looks like you were trying to achieve a Meta build of sorts. You aren't quite there, so I'd suggest checking out a cookie cutter
Meta build.
Also, do you know what stats you need to focus on and what the priority of them is? Or how to gem your gear? From what I see, you have a couple gems that you could switch out and it would boost your base DPS nicely.
