Ideally, they should implement a system that categorizes characters by patch both on and offline so that people can stay within a patch and play with others who also choose to do so. I can see these new updates destroying the game experience for some people because it's taking a remaster and making it into something else.
In the current version it's pretty much impossible for people playing alone or just with one or two friends to reach level 99. Because the experience you get is honestly just atrocious. So I really love the new terror zones, making it at least possible to reach 99 without having this "Diablo Chaining" which is honestly such a bad way to play the game. Unless people are feeding you high player count Diablos or Baals, you aren't reaching 99. But if you have people feeding you high player count Diablos or Baals, then there honestly is no real difference between them doing that, or them sitting around in town to let you farm high player count Terror Zones.I also don't understand, how the current Terror Zones could in any way be worse than Diablo Chaining. At least in Terror Zones you are doing something yourself, unlike that Diablo feeding that is necessary otherwise.
