Not sure, never seen anyone do that.
1). I’ve never said I dont like classic. Matter of fact, I stated I would probably try it out, though I doubt I will ever hit level cap between being playing retail, work, and other hobbies.
2). I’ve never seen anyone bash classic, although I have seen many posts from people stating it’s not as good as people remember, pointing out why private servers are close to original but not exact, and defending retail from people who no longer play but act like they know exactly how retail is.
There has been more bashing about a product by classic supporters to retail than vice Versa.
