I've been fiddling with this army since I made the list with the Crusader, and I am trying to find the ideal combination of units to support the knights.
The list that I took to a tournament and have done relatively well with was the list above with the Crusader, but I swapped the Land Speeders for a Culexus Assassin and did some other minor tinkering. I really liked how it played, but I ran into the issue that the Marines were simply throw away units that didn't contribute to the battle once they were out of their Drop Pods. And while the Drop Pods were helpful to have immobile ObSec units that could hold objectives, the list really suffered when it came to taking objectives.
So I took another look at the army, and this time I thought about running all Land Speeders. This is what I am considering now:
Baronial Court
Knight Crusader: Baron, Rapid-fire Battlecannon, Avenger Gatling cannon, Stormspear Rocket Pods. 470pts
Knight Errant. 370pts
Knight Paladin. 375pts
Ravenwing Strike Force
Librarian: Mastery Level 2, Bike, Shroud of Heroes. 120pts
Ravenwing Darkshroud. 80pts
Ravenwing Land Speeders: Assault Cannon / Heavy Bolters. 70pts
Ravenwing Land Speeders: Assault Cannon / Heavy Bolters. 70pts
Ravenwing Land Speeders: Assault Cannon / Heavy Bolters. 70pts
Ravenwing Land Speeders: Multi-Melta / Typhoon Missile Launcher. 85pts
Ravenwing Land Speeders: Multi-Melta / Typhoon Missile Launcher. 85pts
Ravenwing Attack Bike: Multi-Melta. 55pts
Total Points: 1850
Model Count: 11
The idea with the Land Speeders is that they are going to be a hell of a lot more useful than 12 Bolter Marines and 3 Melta guns. The Tornado pattern (AC/HB) have the speed and range to be effective anti-infantry, which should be significant when coupled with the Knights. The two Typhoons and the Attack Bike give a much needed anti-armour punch.
If I know I am not getting the first turn, I can leave the Ravenwing in reserve and have them come out on turn 2.
The one thing I am not sure on is whether or not it would be wise to swap out one Typhoon and the Attack Bike so I can fit a Culexus Assassin in the list to help with psychic defense.
