You can just find them in game as you play. It is pretty fun, but you probably won’t have all of them yet. At least I’m only about 1/3 of the way.
The problem is locking rewards behind them that some players apparently feel like they absolutely need to play the game.
Option 1: Create complicated system which loads information about other players on demand, being careful that certain information must always be preloaded before it is needed to prevent lags, while different information can wait for a network request. Must consider the implications of increased network chatter on server load.
Option 2: Just load all the stuff.
Because you don’t fix everything by killing one bad guy. Not even in simplistic video game worlds. Especially not in the world of Diablo which thematically deals with the eternal conflict between good and evil.
I get the impression that some of these people were expecting that Diablo 4 was going to allow them to build a meaningful and fulfilling life around playing it at least 4 hours everyday 7 days per week. And now they are desperately sad and angry and having an existential crisis.
Identically named does not imply identical. Could be totally different communities with the same name. Or there could be subtle but important differences.
Likewise differently named does not imply that two communities are not essentially the same.
Having some form of grouping could be an idea that might be useful to some. I imagine different people would like it to function in different ways.
But it is entirely orthogonal to naming. At the end of the day abc@instance1 is a different name than abc@instance2.
because it is accurate to how things actually work
Because not everybody has been obsessively playing this game since launch. Some might come back to the game after dropping it 1/4th of the way through the campaign. Some have just bought the game now. They will want to know that they can just start a seasonal character and complete the campaign on it.
That would then be an entirely different situation?
