I never decided to play WoW and go against the grain by insisting on playing solo. I simply started playing WoW and enjoyed it, regardless of my solo-minded tendencies.
The early expacs had hundreds of hours’ worth of solo progression through questing. The gear rewards and talent trees were satisfying. The exploration of the world and discovery of how different classes were designed was also very satisfying.
The original expacs had group content for max-level progression, of course, but were clearly designed to allow for solo players to reach max level on their own.
Over time, especially in expansions like Wrath, MoP, Legion, and BfA, we saw more and more improvements made to the playing experience for solo-minded players at max level.
But expansions like WoD, SL, and possibly DF have torn away at this progress. The problem is not WoW itself, but attacks on solo gameplay.
No, to continue your comparison, it’s like I already held a part-time assistant manager position for many years now, but the position was removed suddenly because the managers felt threatened; and now I either have to quit all my other personal commitments to force myself to take on a managerial position I am not comfortable with, or I can clean the office restrooms for free.
No, I’m not the masses, but the majority of players were clearly unhappy with Shadowlands endgame, seeing as how they quit soon after reaching max level.
By the way, I am not demanding that everything be changed, only that a solo progression route be restored. Your content will not be affected.
You will get your wish, though, and the game will die if devs keep copying and pasting the Shadowlands model for progression gate-keeping.
