ok, drazhar + vect + incubi + dais may be a very powerful combination, but its a huge amount of points. about 1000 points in a single squad/transport. You NEED more dark lances or blasters in this list. A mech army would tear it up. Try looking at some less expensive HQ, and switching the dais for a raider with FF and maybe nightshields. Talos is great in CC, but its also the one of slowest unit in our list. It very well might not even make it into combat. Always have at least two ravagers in an army this size (razorwings and voidravens work to).
that is all
