I just think that it would be cool if it was like GW... Once you log in, your in. If you want to switch characters, you hit F12 and it takes you back to your character screen and you choose another character.
I've played several MMOs where logging one character out just takes you to the character selection screen, and I've never felt less secure than in STO. We already log in at the launcher and that's enough.
Since the automatic logout is now after 60 minutes idle instead of only 5 minutes, the "security" argument is getting even older. I bet that most people don't play MMOs at Starbucks and leave their laptop unattended and unsecured for over 60 minutes at a time.
