The problem with 40 people isnt getting them to do mechanics. As we have seen repetition and gear solves the āmechanicsā problem sooner or later, some people just need more repetition (so lets hope they find it somewhere far from me).
The bigger problem is the organization of 40 people through out a game that loses people by the day, and a population that is less and less prone to take part of a team and commit to anything.
When each reset becomes more about salvaging a sinking ship than enjoying the game, or watching less and less competent players coming in repeating misstakes, it takes the joy out for everybody - not just the people āin chargeā.
From a member point of view, knowing the line between disband and another reset is thinn, it forces the most loyal members to a sort of responsibility that feels more like a weight on their shoulders than a fun community. When the raid is depending on āthe coreā , or specific roles, to never ever be able to have a day off for something outside of WoW, the game becomes a choir and quitting is close.
2019 was far from 2005, and 2024 is far from 2019 in this aspect.
Thats why PUGs and GDKPs grew stronger by the month from 2019-2024. From a player perspective they were a low commitment tool that allowed for a egocentric gameplay with no strings attached. Show up when you want, quit when you want, life goes on for everybody. No tearjerking letters of goodbye on the free-to-create forum.
In Classic people knew what was coming (in terms of sizes), yet like always, the drop off between phases was a fact when the nostalgia wore off. Indeed people returned but always in lesser numbers than left and always staying shorter than the previous time. The population profiles of Ironforge.pro will show you this.
In SoD, a version that was launched as something fun and with less commitment for the average players (in terms of a very accessable gameplay, more mapped out grinds, changes to counter them and low thresholds all over) I feel that the population wont accept and stay for resets on end with dying communities and struggles to form groups.
It will die and it will die fast.
