Ive been building a Grey Knights army using Crowe and purifiers. I was wondering if I should use Razorbacks even though the weaponry is expensive and HBolters even with Psy Ammo is kind of meh. I was thinking slightly lager squads would be better,and I could take advantage of the Rhinos firing points with some Psycannon goodness. .so what does the noble BoLS forum think? Thanks ahead of time for any input..
