I don’t think it’s Blizzards intent to make massive changes to the Classic era games just yet. We don’t know what’ll happen after WOTLK Classic. We might get Cata Classic, we may get WOTLK+, or maybe Classic will be over, with servers permanently open for the 3 Classic expansions.
We don’t know what’s going to happen yet. I’m assuming we’re getting WOTLK Classic in what would be as close to, its original state. I’m thinking we’re going to get WOTLK SOM with raid difficulty changes and maybe some other QOL stuff.
People need to stop trying to make the game harder, when it doesn’t need to be. Play it for what it is, and see what happens next.
