Grey knight Purifier horde

This was the first grey knight list that I've come up with. It has increadible shooting, and really plays to the mission strengths really well. It has a lot of problems with Hammer and Anvil deployent, dark eldar with night shields and double lash.

The really issue is the max range 24, the fact that it's relatively easy to kill psy cannons, and the fact that 60 foot slogging marines is really not that hard to kill anymore with cover being far less useful.

And yeah, I know it's boring as crap lol.

It really can just shoot a lot of armies off the table, but the real problem is range. 2 of the 5 games I've played with this list have ended with me having very, very few models on the table, and winning anyway because every model scores,  and it's only 8 kill points. If Nova keeps it so troops below half count for full victory points in quarters I might consider running this at Nova, otherwise probably not.
