I’ve flipped that objective on my opponent as first player too many times for me to ever take it. Ackbar broadsides, demo runs, and bomber wings can all ruin your day with the opening turn. And there is no way to force anything to deploy within long range of your deployment zone, even with perfect obstacle placement.
Beleive me I tried, and again when Bail came out thinking turn one Bail could finally make it viable. But it’s too easy to avoid what you want in that large of an ambush zone.
My first ever full game my opponent chose my fleet ambush and turn 1 demo got behind my ISD. That’s always stuck with me
