Got screwed at Arena

Made it to the ship arena. Got into the first fight. Knew what was going to happen as soon as the battle screen opened. I couldn't move my MC up front and had to watch as the boss killed each of my allies. Didn't bother reviving because I thought they'd reset once I revived. My entire squad is dead and it costs ~10k per resurrection. I don't have that much and all my other units are neither high enough level or even available bc they're on dispatch. Guess it's time to take a break before running laps in beginning Abyss looking for things to sell and low tier junk to help (and letting Fortitude reset so I don't dust my best units). Woo, 50k gold lost because I thought wrong.
