we should be able to access all the worlds through one world like use the login screen in to change worlds that way u dont have to logout login ova and ova
good point...i think staying on one world is good anyway
if you have access to multiple worlds, then you may not be able to keep track of all your accounts
If you want more than one character on another world, that's your choice, convenience can't really be an idea to help the game itself other than player-created traffic.
