"Talking about changes and updates: Which build are you referring to? ;) As you already know everything is subject to change and the dev team is constantly changing things to make the game as balanced and fun as possible. "

Constantly making changes means beta in December.

Q u o t e:
stop makin this : "this little word into some random Blizz staff member means no beta before...."

This is very true. There will still be constant changes up to the day the beta starts, on the day beta starts and also once beta has started.
