Why do people avoid getting better at the game?

What are you considering harder content?

The only time I've seen "hard" content teams disband is when the PF is for a specific phase/mechanic and it's clear the party isn't going to reach that point. Sometimes there's a little salt but otherwise ends in "thanks for your time" and disbands.

A party disbanding after "a few minutes" is about 1 pull so I'm calling BS on that one.

Ive seen that happen more often in wow than FF14. Still, it may happen just like you said.
