To an extent I agree. The wowkiller dream is just that, a dream. When wow Classic came out, I felt it captured the parts of old game design that I have been missing. Of course, its impossible to make a new game like old wow, particularly because the reason the gameplay is so "good" (in my personal opinion) is because its so dumb. Tedium is a key ingredient. Taking ages to do anything, and waiting tick for tick to do auto attack damage? People would lose their minds.

But I don't think its actually impossible. I still have (some) faith in the video games industry to innovate and find the formula that'd become a new phenomenon. Nothing can be the same as the first time, the rpg cat is out of the mmo bag in that regard, but I do think there is some mix of gameplay, world design, lore construction, and community interaction, that can bring a new game to the same heights as old wow.
