What they should had done

Is roll back to the previous version of the game as the patch is unstable. Now we have to wait for weeks if not more to be able to play the game.

This is what any other dev team would had done if they rolled out such a unstable patch, roll back, work to resolve the issues then release the patch when it's ready.

But surely they will release the new content today along with more packs while the game stays unstable.
