Don't slot power bolt.
Take your main hold (dominate) at L2 and 6-slot it.
Drop power blast, take confuse in it's place and snipe at 35.
Where is the accuracy in total domination?
Whirling hands could use 6-slotting.
Try to cram stamina to L20.
Slot terrify with acc, damage and recharge.
Only 3 slots in total focus=[censored]???
I would disagree in part with Max here - I think taking Confuse is right (it's just too good to leave out) but I would not drop Power Blast - the reason for this is leaving it out will gimp your domination build up which will be bad in PvE and terrible in PvP. You could fit it in to your current build by swopping Mass Hypnosis for Confuse.
Energy Assault has probably one of the fastest attack chains, but I think you will want both of those early ranged attacks.
The other thing to say is to try to get Aid Self from Medicine Pool in there. It's a real pain but I could not manage without it, a bonus is because you have Power Boost, it will boost the heal from aid self.
Ya could always slot a recharge in power bolt. With hasten that should build your dom bar.
I really should do something about this signature.
yeah, PRAF, domination's all what a dominator's about. 
Hasten and brawl I can get a full domination bar up in about a min and a half with on my plant thorns. 
Yes, another build from me. No experience with Dominators or Controllers, so please bear with me.
Haven't done epics, as my Builder here doesn't seem to want to update.. :\
[edit]: I forgot to put in the build. Zomg.
