I really hope all dungeons/ bosses get rid of timers. In the end I'm almost forced to skip a CS. I was even told to re-watch the CS at the inn. I want the intro to a fight before, not after it. XI (dare I say it) did this better.
The clock shouldn't start running before all members have arrived/ reached a certain point (if in a dungeon)!
Also, the placing of the CS for the van Darnus fight wasn't good. Even though it makes no sense to watch the airship flight before you actually depart, it would have been way better party-wise. One of my party members almost snapped when I told him that I intended to watch it (for the first time! Evil me!).
This is Final Fantasy. One of the main reasons I play is the story (among other things).
