The footage is from last month, and was a limited testing ground. Most of the features weren’t even finished and are subject to change. Hence why it’s an alpha, not a beta. Beta will likely be a little different. And vastly different before the game is actually brought to live as an official build. It’s a very long way from alpha, closed beta, open beta, and live.
Speaking of OW specifically.
Also, you shouldn’t be paying anything for the PvP part.
And I honestly don’t know what you were expecting. I mean, it is a new patch. The current engine was updated, which surely makes it way easier for them to implement fixes and changes.
