I STILL hate this client

Can you spend like a year and make this thing less dumb please or at least give me the old client back?

I get removed from the party. . .when I'm by myself. The game freezes at 100%. The game fails to load and I'm staring at a reconnect screen. My collection fails to load. My profile fails to load.

So please, get your ad campaign sorted out, this is a daily irritant.
