I voted! Thanks for putting this up. I'll put my reasons!
I voted for the delay.
The reason is that because Elite is not inherently a competitive game, it's not a twitch game. It's a game about immersion, #1. Much of this immersion is designed around the idea that this is a dangerous, unregulated universe. As a pilot, we have these huge expensive ships, and we stand apart from the vast majority of the population of the universe. We have a lot of freedom, but a lot of risk. Our lives are dangerous.
It's about choice, and the weight that each choice carries.
It's about the choice of what ship you choose to take, what tool you bring with you to the job.
Ship transfer on its own mostly just means that your choices carry less weight in many situations. With transfers being instantaneous, the choice of ship no longer carries any weight, aside from cost.
Cost is definitely relevant, as weight to be placed on a choice, but it's a bit of a trap. It means that you always have the option of just "waving away" the risk at any point with cash. This does not add to the game. Commanders with loads of cash already have this option largely available. They can just buy more ships.
I'm starting to tangent a little bit, but I'll just wrap up with this. money as an end-all-be-all weighting for the cost of a decision does not add appreciable tension to the immersion of the game experience. It only amplifies the feeling of 'grind'. It doesn't add "character," and every feeling should add character.
I like to reference a statement put forth by Valve back in the earlier days of TF2 when they were doing balancing of the characters and adding new items. Whenever they'd add a new item, like the flare gun for pyro, for instance, they would make sure that they weren't just giving the character a new ability JUST to make them more powerful. The idea was always to add choice to the player, but not necessarily make them more powerful. Furthermore, the choice offered to the player should always be in-line with the character's existing style. They could have given the pyro a regular gun as an option, and just tuned it so it was balanced... but this would be against the essence of his character.
I feel the same way about Elite. Having instantaneous ship transfer WOULD make things easier to the player, but they do NOT fit with the "essence" of the game. They weaken the feeling of the game in general. Yes, you can explain it away with pseudoscience technobabble how you want, but from a gameplay sense, it is anti-elite. It reduces the weight of choice and the feeling that it's just "you and your ship" and the consequences that come with the choices you make.
Adding the time delay means that even the players that have more than enough money are still playing the same game as everyone else, and the players with less money who are making smaller shipping transactions are still playing the same game they were beforehand. It adds convenience, in that you don't have to make the whole jump yourself, you can take a break from the game and come back and your ship is there. It also adds immersion, because you get a feeling that there are things happening even when you're not at the pilots seat. Having the delay ADDS to the feel and immersion to the game, rather than reducing from it.
