I want to ask if there's some way to do this, because it sems many problems are tied to the new version and I'm lacking time to check those things to provide feedback. I recall some thread from official staff where they mentioned we would be able to uninstall every patch and effectively choose which version of the game we get to play.
I guess uninstalling could do the trick.. or will the game default to last patch on reinstall? 
I would like to request this implemented (version selection change, either trhough impulse or some installer)
Not trying to start any discussion about patches, just wanting to know my options, thanks for your time.
