Just had 50114 on “Defend Caspian IV”
It’s the most valuable mission, with up to 80000 to play with… I spent just under 30000 getting 5 MIRV cruisers, 3 heavily shielded ‘tanks’, and a few squadrons of fighters, since you get absolutely swarmed with fighters at the start. Only one of the tanks died, and some of the fighters. I suspect 60,000 honour would be achievable on that map. Someone probably has more already.
I wouldn’t worry about honour nerfs etc… I don’t think it’s supposed to be hard to unlock all the toys (although 2 items show locked on the build screen, but don’t even exist in the fleet HQ ), it’s just a way to try to overwhelm you a little less at the start (doesn’t work so well though, LOTS of toys even before you unlock anything.)
