Currently, we have MP0-10... It is already super spread out and hard to find a group for things,ESPECIALLY on hardcore mode.
Now with RoS, we have different game modes and pretty much the same amount of difficulty modes.
I really worry RoS will suffer the same multiplayer issues the current version has. We need to be able to queue up for multiple difficulties.
A valid concern that I also feel worried about.
It's true that Reaper of Souls will have a Campaign and Adventure Mode (you can read a bit more about Adventure Mode here), but you should still see a healthy pool of multiplayer games. We anticipate a lot of players will spend most of their farming time in Adventure Mode, which is typically when/where players will want to group up,
So essentially, the already tiny population of public players will further diminish slightly by splitting the game into campaign and adventure mode.
and you'll be able to join a clan or community for even more social options.
even more (private game) social options.
To answer your question specifically, though, there are nine different difficulty levels (Normal, Hard, Expert, Master [unlocks at level 60], and Tormet I-V [unlocks at level 70]) and currently you’ll only be able to select one difficulty whenever queuing for Public Games. This is because, right now, there’s a pretty significant difficulty jump between each setting.
I'm currently playing Path of Exile and even though I've completed cruel (equivalent to nightmare in d2), since my gear still isn't good enough, I'm totally fine with farming more in cruel before moving onto merciless (hell in d2).
Now everyone is entitled to be able to play through normal to inferno in 1 run without any backtracking to farm. Just play on any of the 10 difficulty settings that you feel comfortable with which begins at super fucking easy.
We’ll definitely keep an eye on things, and if finding games becomes a problem then we’ll be sure to communicate that to the developers
Finding games is ALREADY a problem. Thank you so much for the console matchmaking system we were given.
