Just played 3 battles thru really quickly. Ships now do seem to want to keep their distance much more from enemy ships, making Keep Moving a lot more effective.
Unfortunately it seems like your ships will happily cause pile-ups with each other in order to keep some distance from the enemy. The 3 battles I played just now, I ended up with a lovely minimum range sized gap between my ships and the enemy ships, but all my ships were parked on top of each other try to keep that range.
Honestly tho, this is just a minor thing compared to what it was like under 1.11. At least now my traffic jams can keep firing
