Moving to '6' stands in the Assaults, Devastators and Scouts while reducing the AVs to '3's is actually an interesting idea and might be worth pursuing. I would suggest checking out the AV costs a little further Mathematically
- The Land Raiders are too expensive at 325 for 3, 250 or perhaps 275 is possibly more appropriate.
- The Predators ought to be 225 for three
- Whirlwinds ought to be 250 for three
Note:-
- The list designers usually add 25 points to smaller formations as a 'tax' on high activation armies
- I did not find your updates in the list I just downloaded - the vehicles were still in '3's.
275 for three TBolts and 375 for three Marauders are both interesting, and *
might* work, though these would need to be tested as three of any a/c can quickly become overpowered - see the BA thread for more discussions . . . . .
All-in-all, a very interesting take on the 'standard' codex list that reflects larger companies with less access to the usual kit, that will be slightly more geared towards 'ground-pounding'. Using Sabres and Stalkers gives further colour, while making everything a standard '6' units will have a significant impact on the usual air assault lists tending to make that option slightly more expensive in a subtle way, which in itself may not be such a bad thing.
