Yeah, I think so, most of us played the beta with no problem at all, the only problem we had was the servers getting overwhelm by loads of players specially during the open beta.
So, why suddenly this AVX thing pops up in the release? It does not make sense to change the launcher adding the AVX request to play now.
From Blizzard they try to tell us that this problem is hard to fix, but that is even harder to believe when you consider the huge changes they had to make since the beta we all played.
I honestly think this will be fixed on Monday as I expect since I already bet yesterday on Reddit we wouln’t play this weekend after the first day reading those blue posts.
