This is my whole thing, I'm trying to get rid of that mentality for myself. I bash it for being a 15 year old game, but I just don't want to be ultra min/max. If I wanted to do that I would be raiding in retail right now. It's fine if people want to take the game serious but man I just can NOT be bothered with that shit.
I also find it very ironic that reddit in particular were always like "Classic is about having fun and playing what you want! Who cares about meters when you're just killing bosses with bros" and then the community somehow became significantly worse than BFA players in terms of telling you that you're playing wrong.
The only wrong way to play classic is to play a female dwarf hunter. What is wrong with you?
