Grey Knights - 1850 Tourney list

I was reviewing the Grey Knight Codex again and wanted to do something a little different but keep inline with what I love...Assault Cannons, Flame Templates and Plasmaguns.

I found a list that I like and think it will offer some challenges to both playing and playing against.

Here's the list:
Coteaz
Purifier Squad x5 ; NDH, NFHx4 - Razorback TLAssC, Psy, Dozer
Warrior Acolyte Plasmaguns x3 - Razorback TLAssC, Psy, Dozer
Warrior Acolyte Plasmaguns x3 - Razorback TLAssC, Psy, Dozer
Warrior Acolyte Plasmaguns x3 - Razorback TLAssC, Psy, Dozer
Warrior Acolyte Plasmaguns x3 - Razorback TLAssC, Psy, Dozer
Warrior Acolyte Plasmaguns x3 - Razorback TLAssC, Psy, Dozer
Warrior Acolyte Plasmaguns x3 - Razorback TLAssC, Psy, Dozer
Vindicare
Purgation Squad x5 ; Incinerator x4 - Razorback TLAssC, Psy, Dozer
Purgation Squad x5 ; Incinerator x4 - Razorback TLAssC, Psy, Dozer
Purgation Squad x5 ; Incinerator x4 - Razorback TLAssC, Psy, Dozer

1850 pts

10 vehicles with TL S7 AP4 Rending shots 24" - total of 40 shots on the move
12 S6 AP4 Flame Templates
18-36 S7 AP2 shots (short is the expected range)
Sniper of Death
CC unit with a good punch

Handles the mid field control.
Torrents and templates hordes.
Handles the Terminator list.

Am I missing anything?

Is it somewhat droll...yes.
Is it somewhat limited...yes

AV14 can give it a problem but the Sniper should handle them fine.

Your thoughts?
