Forum:Chance of using BB in arena is 1/10 battles?and opponent use it frequently LOL

Good day,

i had observed that everytime i do arena, only 10% is the chance for my summon to use their BB, and sometimes it takes 3 more turns after it is full when it will be used, 80% of my lose is because of the same reason, i am hoping for your kind answer. ..

best regards
