Yeap, 2 and 3 ping [redacted] systems have made me very, very rich in game since I started farming them for cores, also make for handy refuelling stops, though all that loot does take up a fair amount of space.
I do wish [redacted] had more ships though, especially some capital ships to fight against or recover via a certain mod.
Oh and 1 and 2 ping systems can sometimes have damaged [redacted] stations in them, very easy to take down and give some decent loot as well. Though [redacted] fleets still spawn in those systems even after removing the station.
