I have retired my Space Wolves army and am hitting up GK's till wave 2 of Necron models are released. I need a tourney army and
here's the list so far:


HQ - 175
Grey Knight Grand Master (upgrades?)

Elites - 590
5 Purifiers- Psycannon x2, Daemon hammer, Psybolt ammunition, Rhino- Dozer blade
5 Purifiers- Psycannon x2, Daemon hammer, Psybolt ammunition, Rhino- Dozer blade

Troops - 525
5 Strikes Squad – Psycannon, Daemon hammer
Razorback – Heavy bolter, Psybolt ammunition, Dozer blade
5 Strikes Squad – Psycannon, Daemon hammer
Razorback – Heavy bolter, Psybolt ammunition, Dozer blade
5 Strikes Squad – Psycannon, Daemon hammer
Razorback – Heavy bolter, Psybolt ammunition, Dozer blade

Heavy - 405
Dreadnought – Twin-linked autocannon x2, Psybolt ammunition
Dreadnought – Twin-linked autocannon x2, Psybolt ammunition
Dreadnought – Twin-linked autocannon x2, Psybolt ammunition

total = 1695 of 1750 ... i have 55pts to spend, what would you use the 55pts for? HQ upgrades?
Would you change the rest of the army in any way?
please help me to max this lists potential as there are no friendly games in my area its brutal while the wars on ( i jest, we have fun while we obliterate each other).
