I did indeed farm at dav's hope for a while, right when it became a thing. But it was not materials cuz relog is meh gameplay, but something else... Cmdrs themselfs. Like at many other "discovery" POI, plently of live stock content at those times. Really popular among paper bulids, really lots of those was around back then.
Anyway, dav's hope sure is popular only among those, who cant really handle combat at all.
I mean, all of these mats are being drop by npc ships, only depend if they are "trade/civilian", "pirate/bounty hunter" or "military/autority" type of npc.
Simply by killing those of each type, mat farming it can be done at vastly higher rate (especially for g4 ones), rather than at dull and boring relog at dav's hope.
