Where we should attack

Bots: matar bay (it will cut off 3 planets from the rest)

Squid's: RD-4 (it will put 2 planets under siege)

Bugs: I'd say Gatria (lowest defence) but the hord is on Phact bay (which would have been my next target) so go there

Super credit farming: Omicron lv2 (will always spawn a lidar station in the caves and no 2 person doors)
