Their solution is so fantastic.
Attempt to join a game, you were too early so now you're locked out for 2mins. Try to make a game in the meantime, game says you're disconnected from the internet until you finally get to create a game, oh wait it already created the game for you and it didn't let you join while it was telling you to check your connection. Too bad now you need to wait another 2 mins to join a game, but don't join the game you already created because it will be deleted by the time you're able to join it anyway.
Instead of punishing people who are causing the problems, they are punishing everyone. And hilarious I got home from work tonight and signed in to play a game to be greeted by a short queue, I got online and there are literally less than 10 active public games in Nightmare. Exactly why do we need throttled login and game join/creation when the active userbase is tiny because most people are in bed?
It's mental that they would release the game in the state its in, because if we set aside all the server issues it's also buggy as shit and crashes constantly for tonnes of players. It boggles my mind how anyone can give Blizzard any benefit of the doubt on this.
