Divination on the
LoC is good, I'm pretty sure precognition was written with 2 wound characters in mind, add a staff and it's better than iron arm, gets almost all its wounds through and try to kill it
on the ground where it can beat things.
I agree that
LoC is better than a prince, but if you take 2 you don't get any heralds and you can only take 2.
Unless you go double
CAD, 4 squads of horrors is plenty of warp charges

1220 for 4
LoC and 396 for 4x11 horrors makes 1614, drop one
LoC and take some heralds for a daemon factory at 1500

.
I see your point, but how often do you get invisibility and how useful is shriek? Telekinesis has 3(ish) answers to vehicles so 50% chance of something to deal with that issue... What am I missing?
I should add that the reason I'm thinking along these lines is the

ing superheavies that my friends bring because my list is apparently
OP.
Don't want to assault them, best case I probably still lose my
FMC(s) in the explosion, so I thought stay in the air and telekinesis while the
LoC and other
DP dodge it and try to murder something near objectives?
