This isnt a big feature but it will make so many people happy,
CCPlease give a button to log out to character selection screen. or a character switcher button. something. it would save so much time from having to close the client and reopen to select a different character on the same account.
The launcher is basically a pretty skin for the old Exefile which is (hopefully) scheduled for replacement as part of the 64 bit client upgrade promised soon™. I doubt we’ll see any development effort invested in the old client. Whether the new client will allow painless character switching remains to be seen - we can hope.
It has been proposed over and over again, and the problem is legacy code. CCP apparently can’t do it because the client can’t cope with a character switch.
