Yea I didn't know how competitive that would be but it seemed like it would be a lot of fun for me lol. But here is the other list that I was thinking about which I think should work better.
Hq- terminator librarian, force weapon , hood = 125
Elites- Assault terminator squad, LRR, TH/SS x5, flamestorm cannon x2, TL assault cannon =465 (hq in LRR)
Troops- Assault marines x6, razorback, chainsword/bolt pistols x6, TL plasmagun, lascannons = 173
Assault marines x6, razorback, chainsword/bolt pistols x6, TL plasmagun, lascannons = 173
Assault marines x6, razorback, chainsword/bolt pistols x6, TL heavy bolter = 138
Death company dreadnought, blood talon w/ storm bolter, blood talon w/ meltagun = 125
Death company x6 chainsword x4, bolt pistol x6, power weapon, power fist = 160
Heavy support- Vindicator, demolisher cannon, storm bolter = 145
Vindicator, demolisher cannon, storm bolter = 145
Stormraven gunship, TL multi-melta, TL lascannon, bloodstrike missiles x4 = 200
Total 1849
So lib and terminators in LRR, death company in storm raven, razorbacks with las plas in back, LRR razorback with bolter and Vindicators forward and SR drops black death from above hopefully turn 3
