When I get round to it, my next army is going to be Daemon Hunters
.
I've opted for an Inquisitor with retinue, Grey Knights, and probably Inquisitorial Storm troopers.
Though I'm not too sure how legal that all is
Culven is spot on about taking losses in such a force, so I would certainly recommend getting Storm Troopers at the very least.
Mainly as they're another target for the opposition to shoot at.
