I remember back only a month after A Realm Reborn came out, when I started the game. People were expecting you to skip it and watch it in the inn.

I tell people (the few times I do it) to watch the cut scenes. Sometimes I see some people actually say "I'm skipping them and watching them in the Inn" I say "Its Final Fantasy. Take your God Damned finger off the skip button and watch the cutscene!"

I don't wait for boss fights though. Thats where I draw the line. Even if half the group is new. Most of it can be 4 manned while waiting for them to finish the scenes.
