Seems like a good build, but more on the PvP front, i'd lose a couple of hold durations and replace them with recharge rates as this will drop toggles, so hitting them will be more important than the length they are held for, especially with the 50% reduction in accuracy for PvP. Love the play on words in the name by the way 
I've been thinking about trying a Grav/Energy Dominator in PVP. This is a very useful post since I haven't had time to read up on Gravity. I would probably take Bone Smasher instead of Power Push myself, though.
Yeah, kinda looking at it, Bone Smasher has a much higher BI than power push... Power push however has one serious knockback component, which turns out to be amusing in hunting down people with TP/SS/SJ in Bloody Bay. However, I really should get something with a nice -fly component, but other than holds all I can think of is air superiority.
The imo's should have -fly right? They do for Ice/earth/fire at least, not played grav before so dont know for sure

I'm not sure, all I've noticed is people hanging about in midair when I've immobed them with anything, the holds drop your fly toggle anwyays, so you plummet to the ground nicely.
The trick with this build is to use wormhole and then dimension shift to effectively cut any group of enemies in half, Dimension Shift is IIRC unresistable, hence it can take tanks and scrappers out of combat easily.
The slotting's not perfect I know, and so far I'll only make this go up to 40. Ancillary pools might sway my decisions.
Also, I think whirling hands is a bit duff for PvP, but it really helps in PvE situations, hence why I'm taking it for now (But might drop it in a higher level respec)
