I'm not trying to sit and watch an entire battle of someone +5 levels ahead of me and 10k+ power more than me thrash me around and utterly pulverize me in both SWB and Matsuri. I won't rant about how messy the ranking are for said events, but re-add retreat. If I know I lost just by the look alone and line-up i'm facing, I'm not going to waste my time watching me lose. I can just move onto the next battle.
