just saying Aun'Va is saddened everytime a commander puts skyfire on a iontide. They are much better suited to anti infantry roles.
EWO = good great, don't deepstrike terminators anywhere I can see them, VT = not a good choice on them, compared to any other option listed. Note the broadside up there is just a single broadside.
broadside x3 without skyfire: 12 shots = 3 and 2/3 hits, 1.22222whatever fraction that is, of a
HP lost.
STILL BETTER THAN AN IONTIDE.
just saying
EDIT: Also you can get into the psycology of forceing your opponent to Jink and just look at the number of hits. Once again the iontide is not that great IF we look at more hits = more likely to cause a jink.
Also for your list above, your commander has very very little need for the C&C node, and the broadside unit might as well drop one target lock if you are keeping the whole unit together.
IF you fire interceptor the gun drone can't fire the quad gun anyways, durring your turn that is. The commander can shoot it in your opponenets phase and still give his benifits durring yours.
