Yeah, when they start repeating endings (T5=TTT2 for them), the arc has outstayed its welcome. -_-
One just needs to beat the living crap out of the other in canon so they can just move on in the next game.
Yeah! Both Yoshimitsu's and Bryan's endings were disappointing because I felt like I had already seen them before. :/
I think both characters would greatly benefit from a new storyline with more narrative potential. Yoshimitsu could face again Kunimitsu and we could find out why she is now apparently blind. And Bryan could have a new storyline where he faces again the guy who once was his detective partner.
