Shadow priest help!

[Laykra]

I feel that I have no controll over my rotation since im switching back and forth between CoP and AS while also switching out other talents. So I wanted to try and stay in one "spec" or talent group if you prefer to call it that. So I hoped you guys would be able to help me out here choosing. Im currently using Sandman pouch (stage 5 2/2) and Warmongering Combatant's Medallion of Cruelty / saberblade talisman
My stats are currently:¨
Intel: 5366 / 5701
Crit: 28.48% / 21.87%
Haste: 14.64 / 18.54
Mastery: 44.83
Multi: 17.44
Vers: 6.16
I`m also have no Tier pieces and Im still missing a legendary ring
My priest is named Echolord on tarren mill if there is something I forgot to mention, thanks in advance!

I don't get your question. You're just asking us to help you make a sub-par choice based on your foibles and personal preferences.

You have "rotational" control over both specs. If you prefer to min max then certain talent choices shine on certain fights. If you don't care about min-maxing then pick the talent choices you prefer.

Play what you find more fun, your talent spec is practically irrelevant outside of heroic progression.
