I quit before Shadowlands released, before their weirdness to sniff chairs and drink breastmilk began to be shown in public. I assure you, it's the same blizzard with worsening and worsening monetization strategies year by year and I vowed to never give them a dime of my money ever again when I quit. I started in actual vanilla WoW.
The lore is a mess, the characters are a mess, the story is a mess, the gameplay is a bloated mess. The only way to make it "good" is to reboot it.
But people forget, even if they brought Metzen for nostalgia brownies (Trust me, thats the only reason he was brought back, he himself said that he doesnt have creative control.)
Its the same people, its the same people in the studio that have been mucking up the game forever. They hook you in with pretty cinematics, and people who have connected their personality with the game are too stubborn to quit or all their friends are there. I was one of those people, the people that play WoW hate WoW mostly, but still play cause its the only thing for them.
