Are you serious?! That's literally its selling point. Vast, complicated, manual, sim.
But its not though .... ED is in no way complicated compared to the X series or EM for example. Its actually reptty simplisistc already in the grand scheme of things, but there is enough 'sim' in there as well, from that point of view the game is fairly well balanced.
And even if you had instant ship transfer it can still be that game if you want it to be, you just choose not to use it, it doesn't unbalance the game because you are not being forced to use it. I don't use docking computers for example, why would you? But some people do, the fact they are in the game doesn't devalue the game or make it unbalanced.
I'm not advocating instant transfer btw, there should be some delay. (5mins per 100LY is what I would go for)
