Well in four years, several accounts, many clear-saves and almost daily engagement (retired) then of course I have made a huge number of jumps (I couldn't venture a guess) but those are spread-out over time and that is why I look at your "massive amount" of jumps as misleading as that reads to me as al large amount in a short time. (That is my impression so is probably at variance with your intent.) I would suppose that most players don't sit down and just do loads of jumps one after another every time they play. That would make no sense whatsoever. Taking the example from further up the thread - Colonia - that trip is now not very onerous at all if you are just wanting to get there as quick as possible and even if you were just going there to do the single engineering mod and come back (sounds crazy to me) this is not a typical playing session - it is a specific purpose not (oft) repeated.
So to me the galaxy is much shrunk since I started, and I was not in at the launch, so the repeated call for shorter travel times rings hollow in my ears (OK, in my eyes).
Think trading, particularly rare trading routes, as well as road to riches, and federal/imperial rank grinds. There's a lot of jumping done in short sequence with those activities. But again, I don't think it's the travel time that's the issue. It's more the repetitive sameness. If that could be improved with some more variation, or some alternate interesting or challenging mechanics, it could positively impact the gameplay experience of all players.
