Interestingly enough, last point has been bone of contention for a long time. And I mean years, in old forums. I can salvage any wreck I like but I cannot tractor it if it is yellow. That makes flying a noctis to be a particularly useless exercise for me.
That said, the third option I have observed is a noctis being part of an Invasion response fleet. In that case they have to be part of the team, because they could not tractor otherwise. So, all this complaining about people “stealing my stuff” when, 1) salvaging has never been illegal and, 2) I cant get near the wrecks now, because everyone else is hoovering them up from within fleets. So, adaptation has been swift and (partly) effective.
The irony is, I was only scavenging in venture in first place because I was hunting the rumoured ore anoms. Never found any and just salvaged whilst looking. But if/when they appear, that will def add a new payout mechanism to Invasions And might change the current salvaging-only dynamic as a consequence?
