The idea is...

3 dreads is main antitank, 36 Grey Knights give 72 stormbolter shots to kill stuff from far away. The BC joins one of the squads to pump it up and is basically there to allow me to get the dreadnoughts. Inquisitor + Retinue is a stable firebase that can shoot at light armor and troops.

I have a bad experience of playing with people who kill my dreads fast despite cover etch and hence want to ensure that even if those 3 die I will still have a chance to take AV13+ armor hence the meltabombs.

Ideas?
