My favourite bit from the other DA list is the Ravenwing formation. It was big enough to be a nasty assault formation, not to expensive and could garrisson which was immense without becoming overpowering.
Yours, an 8 strong scout formation, I think is too nifty and would be very hard to balance, all that scout on such a fast assaulty platform would cause the enemy a lot of problems.
4 bikes (normal), 2 attack bikes and 2 shooty speeders all achieved a very different effect formation wise, but only required 1 new unit (the attack bike) and kept the use of scout to the minimum. And was the correct fluffy size
I think you should keep the DA commanders. That is the SC gets Fearless and the other characters swap Invulnerable save for Fearless. They are a neat, characterful change.
EpicUk has concluesively shown that no air cover is a real problem, I would allow 1-2 hunters to compensate.
Your stats have too many variables. Just pick one stat line for one unit, forget about the OR its not needed.
I am al for plasma on tacticals. They have less shots than the devs so it affects them less. Also Devs are very sensitive to price increases as thye are a smaller unit and more likely to buckle under fire.
Tried lots of stuff with the terminators. ultimately they are best left alone. they have the global special rule about becoming fearless and can have a fearless chaplain added. Really thats enough to make them stand out.
Your Areas is a bit too good FF wise
In fact it is better than a Baneblade! And its still a silly tank
