I love my knights but there is something missing, mostly lack of long range shooting and low
ap weapons. We are a shooty army, so I have been thinking about adding more shooty stuff to them, dark angels can do this as they have access to a lot of plasma, something we dont have.
If I did it, would be something like this, Libby with divination, 5
tac squad with flakk missiles, black knights.
Libby goes with
tac squad and goes on quad gun for very cheap flyer defense and objective holding and black knights are just amazing.
I dont see what deathwing knights are worth it, adding things like bikes for speed and plasma is a great addition to the grey knights.
