When participating in Budokai, if you make it to the semi-finals and are the second person(or team) to fight (and win) you are now at a disadvantage compared to the first semi-final match (the person that won). After the second match is over, there is no break between that match and the finals match. So you don't have anytime to change your gear for the final match. If it is possible, I'd suggest having a short break of a minute or so before the start of the finals.
Thoughts?
