How are players matched in multiplayer, after difficulty selection?
Solution 1:
I have no official information, but this is what I know from my own experience:
- Character level is taken into account and it will match you with similarly leveled players, or if you are level 70, it will match you with other level 70 players only.
- Paragon level is not taken into account.
- Equipment or stats have no effect on matchmaking.
- Only players playing in the same region (regardless of their physical location) will be matched together.
As long as there are players on a certain difficulty, you can be matched with them.
