After 0.8, the core systems became strikingly desolate. All the fleets I encounter are small picket fleets, and there aren't that many of them. Pre-0.8, it wasn't unusual to see huge fleets with two onslaughts patrolling Corvus. Now, I'm lucky if I happen by a Dominator or an Aurora. Capital ships are an extremely rare sight.
Because of this, I have nothing worthwhile to attack with my enormous high-tech fleet that I spent so long building up, except for [REDACTED] if I go into a three ping system and make an effort to deliberately face multiple fleets simultaneously.
It would be nice to have more big things to kill.
