I haven't been to Jaques in a high-combat ready FdL but that sounds like a lot of fun, especially if I'm not the only one who can do it. Not sure how flying Robigo/Sothis missions would be changed by being able to transfer a ship - I fly out in a long range ship and then slowboat my mission back, or I just use a long range ship the whole time, again, doesn't affect me if others do this.
God, yes, I've done PowerPlay but I wish I hadn't. PowerPlay is an example of really poor game and challenge design that Frontier is becoming very good at finding new and inventive ways to create. Instant ship transfer is a mechanic designed to enable fun and better opportunities.
I would not be opposed to very small delays on ship transfers, but only because right now I have had times where I have gone "oh, I'm gonna have to transfer this ship in order to put this module on it. . . nevermind" and stopped playing, and this would at least let me go "I guess I'll do it tomorrow" when I go to play elsewhere. Some people have to do this game an hour at a time, and putting arbitrary waits on things doesn't increase fun.
It's a game, and for me, all design decisions, every single one, should be based first on whether or not it enables fun or restricts it. If it restricts fun, there has to be a compelling reason (gameplay balance, affecting other players, etc). Because Frontier refuses to implement anything like a real player economy allowing module or money transfer in game, there's very little reason to ever restrict things for affecting "the galaxy" or the economy or something, because the game is designed to remove player agency and ensure that individuals can have little to no effect on the galaxy. So really only balance reasons matter here.
So far as I'm concerned, 2.2 is looking like a perfect update, adding quality of life things (storage of modules, ship transfer, and so on), and even the fighters, which I fully expected Frontier to botch and would have lost money on, are going to be craftable/replaceable on the ship, which was something I felt strongly was absolutely important.
So ship transfer is good, great even. Instant enables the most fun, if there has to be some kind of time limit arbitrarily it's something that should be added later, when exploits present themselves, and not right out the gate. Laws and restrictions should be a response to things that have happened, not preemptive, especially when the stakes are so low.
