It's funny how when you prove someone wrong and they get so upset that they have to resort to insults instead of proving you wrong. That's how you can tell when you are correct.
So you think its possible to compare something you haven't experienced in a decade to something you just watched and objectively compare the two? You do realize the human brain isn't perfect right? We are filled with false memories, unreliable memories, altered memories, etc... The very fact you can remember something happening that never did is proof that you can't objectively compare something from the past with something from the present.
Not sure if your a virgin or not so Idk if you will have experienced this but most people look back fondly on their first time even if it was shit and some will even compare it to current sexual encounters and because of nostalgia they may rank it higher than a current hookup even though if they had had both sexual encounters today they would say the first one was a shitier experience.
But I'm sure when you eventually get sick and tired of classic you will just blame Blizzard saying it's not real Vanilla because they made skeleton's despawn faster.
