Ppl with get borred when doing ninja exam and lose, every ppl want rematch ninja exam they all should go out 1st and open. so if ppl want do it so fast, its better with Rematch / ReChelenge *on behind Retreat *on.
sometimes much ppl should do 1 lv exam 20 - 100 times :v its need much time for out from battle field and open exam.
example, much ppl doing exam 100 ++ and doing it so much times.
if that problem from pet, talent or lineup. well we already have Talent *on for exam, and Line up if want change ninnja. Just need prepare them, 3 ninja already in our bag
