The studio fight history lists both attack and defense. Or at least most of them. Some appear to drop out or get suffled out of order or something. Anyway....
The same for duels would be nice. There are many duels that I start and lose that I would love to see the replay for. I know I could just not skip them to begin with, but I'm more likely to spend more time in game watching a replay I want to see then watching the duel the first time.
