Fair enough. I've been wrong about alot of things before. Even I was lured in by the new toy syndrome of Brawl and the story of Subspace Emissary. Was never really allowed to play it cuz my parents would never let me get a Wii. Then I got 4 on 3DS, thought it was amazing but then started playing PM more so I technically DID go back to Brawl by modding it into a less awful game.
Or it's just a simple matter of "hey this is the newest smash"
Also sometimes opinions change. Look back on yourself, and virtually any smash player, and I bet you can find a time where you hated on and despised the competitive scene cuz you believed the BS that "they're playing the games wrong" and that all items and stages are the way to go. Times change, people's tastes change, and so do their opinions.
