I have a whine.
It's come up in my AAR game from the adjustment to threat/AI fleet response to turrets and firepower equations. These cowardly snits are running away as soon as they show up on a planet with anything remotely like decent defense, nevermind one that can actually stop their 1500 ship wave. I will feel the trader to be a mandatory option for BHGs soon if threat of 1/5th to 1/3 of the wave continues to be a norm.
Apparently the whole /10 on turrets somehow fed into the logic of when a wave would run for the hills. These are waves that have proven to be able to break said whipping boy with just a little help from some free-float MK IV threat, so it's not like they're really THAT outgunned here. Heck, smaller groups of actual threat from MK III/IV have invaded and died on the doorstep.
Something... odd... apparently happened with the switch, and it may just be unexpected emergent behavior from the adjustment... but I really don't like it. I feel more like a janitor having to constantly cleanup leftover threat from a wave then I'm playing a game.
