OP is right. Classic could be a flop.
But I must admit that it's caused quite a ruckus so far for such a potential failure.
Dozens of former friends and guildies reaching out to one another to coordinate plans for their return. A barrage of fans tuning into podcasts, twitch channels, visiting fan made chat communities, and even holding their noses and posting in the toxic official forums. Well known top guilds vowing to achieve server firsts, former iconic Vanilla players announcing their plans to bring life to their former hobbies in the form of speed running records and epic PvP videos. Players clamoring to join the beta, crying out for more info leading up to the announcement of the release date. Gamers logging into private servers to see how quickly the nostalgia would die, only to find that the taste of a 5 man Wailing Caverns run or their first world PvP encounter in Ashenvale immediately reminded them of why they had dedicated so much time to this virtual world to begin with.
Meanwhile, we see posts like this one, raising doubts and concerns, pessimistic that Classic will allow us to truly relive our fondest Vanilla memories. For many of us, it's all too familiar. We've heard it before, different variations of the very same words that were uttered by Blizzard themselves many years ago.
"You think you do, but you don't."
I know we joke about that quote a lot, but that pissed me off so bad when they said "You think you do, but you don't." Listen motherfucker, you don't know me, and you don't get to say what I do or don't want. Ugh, it still grinds my gears even though we're getting Classic. I honestly want dude to apologize and say he was wrong, flat out.
