Season 8. You can never minimize your client. Every third game your game crashes at the 2-3 minute mark and you end up 3 levels behind everybody else by the time you get back. You suffer much flame.
Season 9. You still cannot mimimize your client. You double click the program to try to start it 30 times. If you are incredibly lucky the client opens and says you need to restart it in 8 seconds. If you click restart, the game closes. If you wait, it will update it for 3 minutes, even if you updated it multiple times that week.
