Beatty, you at absolutely right! Here is my favorite method of handling that with 3 VSD's.
I like to use a staggered formation and I would have my turn 2 and 3 commands as navigation. 4 and 5 I expect X Wings so that will be engineering commands. Using the nav commands to allow me a speed 1 two click turn. This will let me predict where things will be (seems silly but watch). Having the ship's staggered I can force my opponent to move a few ways. Usually within my front arc of something.
While the rebels can dance like a butterfly they don't yet sting hard enough. Wave 1 will change that a bit though, but at the same time imps get a speed 3 as well
