Grav/FF/Primal - critique please

I'm working on a concept toon with this power set and I'm finding it a bit challenging so I've tried to come up with a build to help improve the experience. I mostly team with friends but will solo as well and find his damage is abysmal. I'm pretty settled on the power choices though willing to listen to advice there also. It's really the number of slots I should dedicate to each and the best sets in each power where I'm mostly at a loss and could use you help. I used Mid's to put together a build but would welcome any and all suggestions for improvement.

And just to demonstrate how little I know about builds, I can't even figure out how to properly post it in the message. At least the link is there!

As for posting a build, it is really pretty easy. In Mid's, click on "Import/Export" on the Menu bar. Then choose "Short Forum Export . . ." Pick a color scheme (I like Fruit Salad) on the left side of the box. Under that, click the first and third boxes -- the third one will export a data chunk if the link doesn't work. On the right side of the box, choose "Official Forums (VBulletin)" and under that only check "Don't export Invention Levels." Then click on Export Now. The codes needed to post the build will be put on your clipboard, so you only have to press Ctrl-V to paste the build to a forum post.

As for the build: Your choice of powers is OK but your slotting needs some work. Why are you building for melee defense? You have Force Bubble and all of your powers are ranged . . . you have no reason to be in melee. Build for Ranged Defense and Recharge! Use Thunderstrike in Crush, Propel and Lift.

Wormhole is badly underslotted. A full set of Stupify will give you more Ranged Defense. Don't slot GDF for Slow-- it is a hold! Try the Lockdown set. Trap of the Hunter in Crushing Field. Three Thunderstrike, Stupify, Lockdown and Trap of the Hunter put you past the softcap for Ranged defense.

Now you go for Recharge. In PFF, Deflection and Insulation shield, use a Luck of the Gambler Recharge and Defense. Put another LotG Recharge in Hover (and use that second slot in Wormhole). Replace the Def/Rech in Maneuvers with a LotG Recharge. That gives you your max of 5. In Grav Dist., use 4 Baz Gaze (don't use the proc). You can add more Acc and some damage in the last two slots -- an Acc/Dam and a common Damage.

Singy can get some special slotting: Keep the Sovereign Resist proc. Add Acc/Dam, Dam/End, Acc/Dam/Rech and the Resist proc from Expediant Reinforcement. Fill that last slot with a Dam/Mez Hami-O (they are fairly cheap). That will cap Singy's damage, give him great Resistance (since he can't be healed) and buff his mezzing powers too.

Health: use a Miracle proc, a Numina proc and then a Numina Heal. With all the Luck of the Gambler sets, you should have a pretty good amount of Regen, which will reduce your need to heal.

Consider changing Fly to Superspeed. With that Stealth proc you have in Sprint (which could be moved to Super Speed), you will have full invisibility. Full Invis is great for leading Singy into battle. If you need to fly, use a Raptor pack.

Here is what I came up with in just a few minutes. I'm sure that this could be improved.
