Midgardsormr is the only home on FFXI I'll ever have, mostly because of the people who are on it with me. The Red Lotus is a pretty close-knit bunch with quite a few EoFFers. Omecle, Lord Chainsaw, Vaprice, Lionx, and myself Red Lotus members who frequent these here fora, and all of us 'cept Chainsaw (I rarely see him on anymore, but that might be timing) are on quite often and usually available to help out. There might be others I'm not remembering right now, though.

As far as starting over, I've done it quite a few times and it hasn't bothered me yet. Granted I haven't ever bothered to level anything past Lv30, but I still put a lot of time into the characters doing various other things. If anything, I'm enjoying starting over again after quitting and coming back.

It's really up to you, but Midgardsormr is quite a fun place. It's always more fun to be around others you're familiar with.
