Balance changes are not in the beta yet, they only did the features in the changelog.
Also how does "WEEEEEE your update sucks so now give us this!!!!" work in your world?
Setting up beta servers for weeks again just for sweats to play it an hour is just a waste of resources, maybe an option could be that they host it for one evening to test it. Would also weed out some bugs which always happen on releases and hopefully not break everything this time.
