I found it a bit annoying for the ruiner to run headways into incoming ships. this is a mine laying ship, a support cruiser, not an attack ships, so it should stay behind. didn't notice it at first, so I'll play around with switching off auto attack or curbing its attack range. in any case, this could be something that should be done once they come out of the factory. otherwise, they could also adapt the ai routines of the other support ships, which I have not seen so suicidally rushing into battle.
not a huge point, but since mines are not deployed automatically, it's a bit more obvious.
