I tank and heal. If you see me in a dungeon and I'm DD'ing, you very well may want to just kick me anyway (Sylphie has better DPS than I do). However, I'm watching the cut scenes. Watching them in the inn doesn't give you the feel of watching the cut scene then running the dungeon, then another cut scene or two (or three). If experianced players want to kick me, they can find themselves another healer or tank, which would likely take longer then just letting me finish the cut scene.

On the other side of that coin, I would not deprive another player the joy of watching the cut scene, even if I've run the dungeon 50 times already, hate it, and just want to get out. In fact, kicking players for watching cut scenes seems like a violation of the ToS.

3.2 Disruption. You may not in any way disrupt or interfere with the Game experience of other players, including the disruption of Square Enix's computers and servers.
