1000pt Grey Knight noob list

[Abzapp]

This is my first 1000pt grey knight list. I fight mostly orks (semi blob with truks with rocket boys and battle wagons and stuff). 

I came up with this list and I think it would work pretty well but I have no idea. Any criticism, swap out, support, or ideas in general would be very helpful. 

HQ 

2x Librarians w/ storm bolter 

Troops 

2x Strike Squad with two incinerators 

2x razorbacks with twin linked lascannons 

1x Nemesis Dreadknight with heavy incinerator and sword 

That comes out to 1000pts exactly. 

The idea is that the Strike Squads would combat group and the librarians would go with the groups left out of the razorbacks. The dreaknight would go with with the razorbacks and take out the heavy tanks and burn as much as he can with the incinerator. 

What do you guys think? 

I'd be interested in a list with interceptors as well seeing as board control is important now I think.

Purifiers are good to wipe out ork blobs in one round, especially in melee. Cleansing flame and their toasty

Are you playing a CAD or NSFD?, If you go NSF then swap one Strike Squad for a Purifier Squad.

No need to combat squad, Razorbacks would go alone.... (and they will stay behind) or swap a razorback for a rhino, and embark the purifier squad... two flamers in the squad will give the Rhino some threat. I use to do this... for mobility, just Turbo boost turn one. to place them close to the enemy.
