We kind of need tension to recognize the opponents as threatening of sorts. Even if it's not really a requirement it would still be nice to have. In fact most of the disciple fights have it except Miu's.
I mean to be put on the defensive against an opponent who's actually a good match for her only to end up going"Beast-Mode" cause of superior Dou ki felt like a waste to me: especially since I kind of wanted to see Miu struggle at least a tad longer against another disciple.
Well Miu's fights still aren't as bad as the current Renka and Rachel fight with the exception of the Junazard arc.
Agree on the time-skip thing.
