I really shouldn't speak without actually driving a Victory myself (waiting for Core set to come in, curses!) but talking to my manager today about Armada strategies and it was his opinion that Victories and the Empire really suffer in the core setup. Even with only core equipment the empire is always going to be at a disadvantage against the rebels.
Yeah, I haven't touched them yet but I'm not so sure he's right. My plan for taking a victory is to drive at speed 1 with a banked speed command, and hold my fighters in reserve until 1-2 turns later when I activate fighters, pounce on and chip away the X-Wings, and then annihilate any Nebulon-Bs that I know can't escape the forward guns.
If the rebels ever get behind me I'd throw that speed command to crank it up and try to get out of the rear arc. I expect my turn would be wide enough that I can throw off a pursuing CR-90.
And if the Rebel does something foolish like split his X-Wings or charge at me with the CR-90 I can respond accordingly by picking off the former, and shooting up then ramming the latter.
I guess I'm just wondering if more people are doing things like never changing speed and timing their fighter moves off and that's why the Empire has a purported loss ratio. Just because you're driving a victory doesn't mean it's going to be simple to win.
