Did you have the tourney? Terminators without a chaplain is a bit of a waste...
What others say about razorbacks, vindicators slow you down, a thunderhawk is better than a strikecruiser and dreds generally don't work outside of CC - if that dev & dred formation is a garrison without rhinos it needs a hunter...
Try and match speeds together (so vindies with land raiders?) and if you have the thunderhawk consider the old ass/dev filling. Not as good as terminators, but hey hum.
The minimal changes I would consider are...
Tactical w. Supreme Commander, 1x Razorback & Hunter - 500 (BTS)
Tactical, 1x Razorback - 325
Assault - 175
Devastator w. 2x Dreads & Hunter - 425
Terminator, Chaplain - 400
Land Speeders w. 1x Tornado - 200
Land Raiders - 350
Predators w. 4x Annihilators - 275
Thunderbolts - 150
Thunderhawk - 200
3000
(Though I would rather replace the second tactical and assault marines with scouts and terminators, of course I wouldn't use the dev garrison either!)
Going more off your original idea is
Tactical w. Supreme Commander, 1x Razorback & Hunter - 500 (BTS)
Terminator, Chaplain - 400
Terminator, Chaplain - 400
Devastator, 1 razorback (las) & Hunter - 350
Land Raiders - 350
Predators w. 4x Annihilators - 275
Land Speeders w. 1x Tornado - 200
Scouts, 1 Razorback - 175
Thunderbolts - 150
Thunderhawk - 200
Though it is a bit activation light... Got any warhounds?
