One thing that I run into, and wish it would get “fixed” is that when I launch the game through the Beta Launcher, it doesn’t minimize or vanish to show the login screen and then the game screen unless I intentionally select that screen through Windows. With the current launcher, the game comes “forward” and the launcher is removed from the screen. The Beta Launcher should do this also, but it’s not.
I do like that I can select my character and/or other accounts through the Beta Launcher, and that is shows more game-related information. The layout seems more intuitive and puts more information at the ready.
