Ah crap, noticed that stone spears, tremor and fissure will not work with hover ><
I don't have a lot of dom experience, but I do play controllers a lot so my advice my favor that side a bit.
Random suggestions:
- Drop the end/recharge/hold from Basilisk's Gaze. Replace with acc/recharge/hold from Essence of Curare. That will bring your accuracy up to 75% as well.
- Drop the chance for knockback from Stalagmites. It's a mag 6 knockback so it tends to spread enemies a good bit.
- I like Dark Watcher's Despair in Earthquake. Enhancing the -tohit helps keep enemies from shooting back in between bounces and you can pick up a cheap 5% recharge with just 4 slots.
- Replace the damage/range in Fissure with the damage proc. As it is slotted, you're biting into diminishing returns. The proc will provide more damage than the 3% gained to damage and you're likely to be in melee range to use your other powers anyway.
- Consider Powerboost. In addition to boost your mezzes, it will boost the -defense in most earth control powers and the -tohit in Earthquake. It will also boost your defensive powers for it's duration, which can be handy when you're opening on a group.
Cheers for ideas.
Not too keen on the powerboost thing, mostly because i forget to use it, spose i could figure out some easy bind for me to make me remember to activate it 
Well, this char reaching level 40 now, so i fugre i should try make some actual plan for it
The plan i went for it was to get some melee defense (since most my attacks are melee), as well as a dab of recharge for domination. Not sure what i need for perma dom tho.
Also tried to keep the cost down a little at least.
Tips and such welcome tho, not much experience with dominators, tho i am really enjoying this one
Edit: removed flight pool
Edit2: updated with the tips
