Okay, TIL that trying to improve yourself with parses is cheating...
This is honestly the first MMO I've played where it seems the majority of players actively push against attempts to improve at cap. And this is also the MMO with the lowest average skill out of the ones I've played. What's so bad about... not being bad? The cries of "toxicity" and "elitism" when you expect more than the very bare minimum from capped players is baffling.

Disclaimer because I guess I have to: None of this applies to sprouts/casual content. You should never expect perfection from new players. They still need to learn, don't yell at them. If they ask for advice, thank the Twelve, and help them. If they don't ask? It's easy content, the world won't end because Daniel Dragoon in Shisui of the Violet Tides didn't keep up buffs 100% of the time or Harry Healer overhealed the tank every trash pull - move on.
