Wildstar was the only one that tried to go oldschool WoW raiding type but failed big time and it's servers are dead.
The fact that they put the ''Loremaster'' achievement behind raids means that not only the hard raids are done by a minority (normal/heroic/mythic) but even Raid Finder in WoD and MoP was done by a less amount of people than what they expected so in a desperate attempt to bring more people to bother with raids they locked the 2 last Suramar storylines behind Emerald Nightmare and Nighthold.
This brought only negativity however, and people will do these 2 raids just once to complete the quests so i won't be surprised if the next step is to make Raids like the modern age - to be big soloable story events and instead the endgame content will be focused on dungeons, either mythic or whatever they bring up.
