I’ve only had the game a few days now, but I would like to offer a couple of recommendations based on my multiplayer experiences.
One, it would be nice if the multiplayer window saved your preferences across games. It’s rather tedious to reset all my filters every time I want to thin the server list.
Second, one of the best features I remember from the D2 days was the chatroom function of the lobby. People could plan and get ideas together, and it made the community feel much more alive.
I could be wrong and both these things are available and I haven’t discovered them, of course. But if they’re not, I do suggest them!
