2000 points, in house games

This is a 2000 point list I threw together as a target for a tale of 4 gamers type of situation that me and a group of friends can build towards and aim for. So here it is!

Librarian: Halberd, Might of Titan, Sanctuary, Vortex of Doom, The Shrouding, Psybolt Ammu = 180
Brotherhood Champion

GKTerminators x 5: 4 Halberds, 1 Hammer, Psybolt Ammu = 220
GKStrike Squad x 10: 2 Psycannons, Psybolt Ammu = 240
GKStrike Squad x 10: 2 Psycannons, Psybolt Ammu = 240

GKPurifiers x 10: 8 Halberds, 2 Hammers, Psybolt Ammu = 286
Vindacre Assassin

GKDreadnought: 2 Autocannons, Psybolt = 135
Land Raider Redeemer
Stormraven: Multimeltas, Lascannons = 205

I have played a small variation of this at 500 points (really small) and I did not like being outnumbered by the vast amount I was, so I have decided for my full list that I will weigh more on the side of strike squads than terminators. I know that as Grey Knights I will be outnumbered pretty much everytime but I dislike stressing that issue more than it needs to be.

The Strike squads main role will be to sit at objectives (since I dont have a GM to score anything I want). They will also act as a barrier to my Vindacre, which was added for nostalgia, I always wanted one, ever since I started 40k a long time ago.

The Dreadnought should will move with whatever it needs to move with, depending on how melee oriented my opponent is and whether or not some of my larger units need protection from psykers. I plan on putting my Terminators with the Librarian inside the Land Raider and moving up centre or anywhere really, with the Stormraven full of Purifiers and a Brotherhood Champion proving quick close combat insertion, giving a large threat to anywhere I need it.

Some changes I can think of taking the psybolt away from the Purifiers, but I wouldnt know where to shift such a small amount of points. I feel like I have a balance between ranged and combat, but my view is biased. Any thoughts and changes welcome, thanks for reading!

I would knock the psy bolts of the lib and the terminator squad and give the terminators a psycannon.

Unfortunately the Terminators are the one thing I cant change, they (along with 5 PAGKs) are part of the 500 points I have for small games which im going to build up. I could counts as but I really like to have WYSIWYG models
