You have very little imagination, sir. I have four accounts and use them all for different things. You can't have the same commander play the role of a notorious pirate and a fuel rat, as an example. Can you imagine what would happen if you called the fuel rats and that well-known wizard turned up to help. I don't think that would work, somehow. As well as playing different characters when you want, there's other things, like making videos to show say noobs how to play, but if you have the rank of elite, different things happen, so you can't show fair examples. Also, you can be in more than one place at the same time. It's a bit of a pain when you're exploring in the outer reaches of the galaxy and then something interesting happens in the bubble or if a friend wants to wing up for whatever reason. Personally, I can't see how anybody could play with only one account. it's OK when you're learning, but after that, it's too restrictive.
