Rydin,
I didn't mean it that way, even though it may have sounded that way. I was pointing out the fact that everyone says 2.0 will fix it all, and that is still a long way away.
Yes, I would like a mailbox, simply due to practicability of it. 2 retainers may not be enough for some people and having a second character on the same account could work for some better if there was a mail system in place.

The fact that FFXI had it was just said as an example of how mailboxes worked. If there are better ideas out there I wouldn't mind seeing them, since this is a new game after all.
