It feels like that's been flipped in Classic, with a large portion (or even the majority) being tryhards (or wannabe tryhards) and only a handful playing for fun.
The reason behind why this happened is multi-factored, but I would chiefly blame the rise of streaming and esports. Those two in tandem twisted the mentality of the larger gaming community such that now a lot of people feel that all gameplay must be competitive in some sense, must be centered around minmaxing, and must chase the meta in order to be considered legitimate. Dare to play the game any other way and you'll be loudly derided.
