making more characters = more storage space when they add a mail box, no reason to have an alt in this game since you can do it all on one character.

Community issues will happen no matter what, this will just make it worse.
I'll just give an example:
One day you decide to create an LS. This ls gets big, you develop an LS bank with lots of gil. You start to get greedy, so you make a new char. FREE OF CHARGE. Steal the ls bank, give it to your new char. There you go. You are now a very rich level 1.

It will just promote stuff like that.
people bot and buy gil & people rob the LS anyways.


Also, having 1000 inventory space is taking advantage of the mechanism. Pretty sure those other chars are not there for storage.
people do it all the time in mmo's
