I feel like this would be partially based on the type of scene or even the environment of the game. I think social based stuff is a lot easier to do async where as action based items feel like they need to be sync’d just to keep moving.
I also like the separation of sync / distracted / async. I really don’t have the life space to do sync’d anymore, almost always I’m distracted or async, but the problem for me like so many other mentioned is getting the motivation blues when it comes to async taking too long.
