-image to update and -sharearchive to launch the game is a basic requirement for running multiple accounts simultaneously, so yes. Technically you don't need -image to update, but that'd be a mess with multiple Local.dat files. Gw2Launcher also offers using an authenticator, for those that don't want to deal with codes. So, since ArenaNet is ignoring this for the time being, I decided to use your launcher. I'm having a bit of trouble though with the second account not saving the sound settings. I created my first account with the launcher, then added the second account by telling it to copy the settings from the first Local.dat. Everything copied fine as far as graphics and keybinds, but the sound volume is jacked to 100 and won't save when I change it during gameplay. Sorry for bringing it up here, but it's because of this change by ArenaNet that I'm having to jump through these hoops. Thanks in advance.
