Yeah true, although I don't think I used capitals at all last time I killed Ziggy, definitely wasn't maxed out - it was cruisers mostly, Aurora, Furies, Herons and Champs I think - was awhile ago. Anyway for me battle size 400 is boring and too small, there are big fights to be had in this game 4x style vs many fleets at once and these 1-2 scripted boss fights I don't care much about.
I'm on a new playthrough recently in a default sector + Nex mod, battle size 800. When I meet Ziggy I'll try to record it if I can, I think default DP should be around 220-240 for this fight.
Just had a fight vs 2 Pirate Armadas merged plus a corsair, I think they had something like 12 Atlas MkII and about 12 more rows of trash below it.
