As it stands in Diablo 3, 3000 paragon level people are matched with 400 paragon level. I’m not suggesting one player is better than the other, but they have different goals in mind. I spend most of my time trying to find games with people who want to run the same level GRs. I’m not interested in making a bunch of friends in the game, I just want to pug all day. It’s how I enjoy the game. And they should have a better matchmaking system for D4.
In D2, I can make games with level minimum requirements or maximums. I can describe the nature of the game so people are on the same page when they come in. I was disappointed when Diablo 3 didn’t have such a system, and to this day, it remains a problem.
