List of the Week - Grey Knights

So...in lieu of tournaments to keep me occupied, I am going to start a 'List of the Week' series. I am always looking for a tournament level competitive build that tickles my fancy and I have the models for...

I have alot of free time to sit on Army Builder and then test the list out against a few of my standard playtest armies.

To start the series off we have...a watered down Draigowing / Deathwing combo.

Grey Knights:
GKGM - Psycannon, Blind, Rad, Psycho  255
GKBC - Psycannon, Blind, Rad, Psycho  225
Paladin x5 - x2 Psycannon, x2 Naked, x1 MC NDH  320
Techmarine NDH, Rad, Psycho  125
Techmarine NDH, Rad, Psycho  125
GKTerm x10 - Justicar NDH, x7 Naked, x1 Psycannon, x1 Psycannon/Banner  475
GKTerm x10 - Justicar NDH, x7 Naked, x1 Psycannon, x1 Psycannon/Banner  475

2000 pts

Thoughts:
KP Mission-
GKGM gives scout or Counter attack.
GKGM and GKBC attach to Paladins
Techmarines attached to 1 Term unit each

Yes this is 3 KP units netting 7 total KP.
Most of the game the GKGM and GKBC are attached to the Paladins, midfield they split off and support with their own Psycannons and Assault toting grenade goodies.
An enemy unit should get hit by multiple Rad/Psycho grenades.
Between the Rad and Psycho grenades each CC should end after 1 phase.
Yes this will leave them out in the open to get shot up again.
CC is where they want to be over and over again, not in continued combat.
The Naked guys are to get a boost in CC Inv save.
The Banners are there to make the units S 5 to start, getting up to S 7 if needed.
Yes there is limited LR range shooting. movement and 24" has a pretty far reach once you are in midfield.
Could always DS the Term units and just walk the 'uber' IC/Paladin unit across the board. Especially if vs Venom spam.

You could also split the Term units and attach the IC's so each unit has 1-2 Psycannons amd CC PUNCH.
Giving up a few more KP but doubling your chances of netting more KP yourself.

Obj Mission-
GKGM gives Scoring to Paladins

GKGM attaches to non Psycannon Term unit with Banner.
GKBC attaches to non Psycannon Term unit with Banner.
Techmarines attach to Psycannon Term units each.
Paladins alone.

Each unit has 1-2 Psycannons and CC PUNCH.

This gives 8 Relentless Psycannons and up to 4 CC units with grenades.

Aside from Fast units, what do you think would give the list issues?

I had a Libby in the original list but took it out because I think this iteration gave a little more flexibility.

You could drop the Blind grenades, Paladins and GKBC to pick up a Vindicare and 3 Psyflemen. This was the original list but changed because I thought the posted list was better in the endurance game.
