People can’t lock-in for large amounts of time anymore, everyone has pretty much gone casual, and that’s what’s killed raiding.
I remember it would take an hour or two just to summon everyone to the raid via meeting stone or warlocks, get everyone buffed, consumables, ready check, etc.
It was a great social phenomenon when it was current, but there’s no going back to that.
We’ve all grown far too impatient for it, lol. Would you want to stay in a wipe-fest group for hours on end, while people grow exhausted? I think lots of us have endured far too much of that, and have thrown in the towel expansions ago.
It’s not fun when your success relies on other people doing their job, and failing again and again as a result.
Even M+ gets complaints because people don’t want to be locked into a group unless it’s easy and stress-free (no bads).
And that’s not even talking about loot scarcity, and the reward problem/incentive.
There’s no reason to do the same thing on a harder difficulty, unless you are chasing numbers alone. Everyone sees the raid and all the cinematics on the easiest difficulty, and Mythic is just too far out of reach for most, so why bother?
Raiding is pretty much dead, compared to everything else. M+ is faster, and you can get raid pieces via vault as well. (I’d argue LFR is the most ‘alive’ version, and that’s tourist mode.)
