Don't put words in my mouth please.
I didn't say it was too accessible, I like how accessible the game is now. It's way easier to get friends into WoW now than ever before. It's great TBH.
Making a game hard isn't good game design, making the game selectively difficult is good design. You don't NEED to grind a 10 M+ every week, you don't NEED to mythic raid to get good gear, you don't NEED to play the game that much at all to stay relevant.
Legion is good because it keeps players who don't dedicate much time to the game closer in power to those who do. It's the function AK serves. It's why I like the AP system so much.
Vanilla was bad because you had to grind all the damned time to get anything done. The ends often didn't justify the means as validated by the tiny percent of players who cleared Naxx 40. That shit was too hard for the majority of players, which is bad. If players can't see your end content what's the point of it?
I don't agree with you that the game to too accessible, it's great as is.
