Keeper of the Grove burst PvP

I want to know what your rotation is for keeper of the grove burst for pvp.
I primarily use a single target build, focusing on starsurge. My opinion is the rotation for keeper is very clunky, having to balance AP, astral power, and modifiers.

My burst is: make sure DoT’s are up ,drop trees on target, starsurge, incarn (orbital strike) starsurge, wrath, wrath, starsurge, starsurge, wrath, wrath, starsurge.

Most classes have a rotation to burst, but I have found none for balance Druid.
