Slight detail you might be missing there. I only climbed against specifically the triple attacker executor lineups. My specific fleet is specifically made to kill the punishing one before it ever takes a turn.
With the first free ult from Ackbar you can bring the punishing one down to somewhere between 50-0% hp depending on how much you crit/ it dodges. if its still alive you use Vaders first special to reset the turn meter on it.
once Cad bane has taken his turn his stealth expires and then you can call in the falcon with Ackbar to essentially instakill it with the assist from B-Wing.
After that all that’s left is cleanup (Although that’s not 100% consistent is your unlucky and they get contract before Mando dies). I have never beaten either Profundity or Revans capital ship with this strat.
If you don’t believe me try it yourself none of my chars for the ships except Vader and Drogan are build very well so you should be able to replicate it.
If I was beating Profundity or Revan you would be right though. Profundity to me seems unbeatable with Ackbar+B-Wing cause hard counters the ult making the entire strat useless and Revan just kinda kills you (trust me i tried).
