This is exactly right. If I don't feel like watching cutscenes and am, for example, farming Castrum for tomestones... I'll form my own premade group OR I'll sit down, shut up, and let people watch the cutscenes if I'm in a Duty Finder group. The storyline is the best part of any Final Fantasy and I am not going to take that away from other people just because I'm too impatient to wait around for a few extra minutes. Just because someone is a stranger to me doesn't mean I have any right to be a jerk to them.
We're playing an MMO, people. Playing a videogame is already a waste of time. You can wait a few minutes for other people to enjoy it.
