Hi, about the duration of the battle I liked that 15 minutes for 10 days I thought it was great during the week it's great to get more crystals in 1 battle so I wanted to say I liked 15 minutes during the week, thanks a lot.

Hello, well I came here to leave my opinion about the duration of the battle which I really liked when the battles were 15 minutes, but 20 minutes is also good to gain a lot more crystal and experience in a single battle and for me it could stay fixed 15 minutes or 20 minutes, but I really prefer 20 minutes because you can earn more. Thanks.
