"No wrong way to play vanilla" "you could do what you want" "you can do interesting builds and have your own adventures" but when it comes to a play style which you don't want, hey it's wrong? classic dude - pun intended.

As long as you state it as opinion and not actual fact.
My exp so far is most ppl I encounter from classic are like "go back to retail".
You can't compare it objectively based on one subject, which is you which basically negates all the base you have on your argument because of confirmation bias. Opinion is all you have. Otherwise my opinion/exp goes against yours, so who would be right then?
