I hate boxing. It's not fun, it adds complication, expense, you don't meet as many cool people as you would otherwise, auto-follow sucks balls, you don't feel the attachment to your characters as strongly, etc.
Remember, 6 fucking months. If you box an ideal group setup, you will be maxed out before June is over. It was not my choosing, but the server we got was built to enjoy the scenery and not just the destination. After you hit 50 in a week or two, your only option is to be in an uber guild or compete with them... which is a poop-sock nightmare either way.
Sure, I have boxed plenty in the past, but I am confident that there will be groups to be had with this server and plenty of people to play with. It is not going to be convenient or ideal, but if only running one character gets me to the point of burnout, then I probably should stop playing anyways.
