Haven't tried the beta yet, but I wonder if the 3-4 bars are really any better than console. Based on the feedback i've read, it doesn't sound any different. Just the 1-2 bars which would likely be unplayable regardless...
3 bar has only worked for me if it's a stable ping on both ends. All my bad experience with 3 bar have been with people that will get 2 bars sometimes when they join. That said, I can't really say a stable 3 bar is fully acceptable compared to offline.
Comparing to offline, it seems like it would be no different where only 4 bar is acceptable, if even that. On console I've only had bad experiences with 4 bar when the ping wasn't stable for both players (alternating between 3 and 4). I wish we could just see the numbers in real time instead of this color coded nonsense that only shows a reading for the moment you join the room.
Anyways, these devs in charge of the beta seem to have some decent communication. Have they said anything about rollback netcode though? A lot of people have posted about it and they seem to be dancing around that question. No matter how much they fine tune it the way things are, everyone will still be restricted to more local online play. That just isn't possible for most of the world. It's hard enough for me to play online being 3+ hours away from an offline scene.
