Hello there fella. Like you, I also made lots of mistakes in my old account, some are irreversible that I already abandoned it. Im doing fine now with my current account, always placing 1st in SWB, winning in Matsuri etc. You are pretty powerful for your level in terms of BP. What is the problem? You lack better ninjas? You lack proper team composition? If so, please list your ninjas so that we can help you build a competitive line up. My advice is dont focus on power right now and instead save coupons to get better ninjas, not with rng events but where you can surely get them. My next advice, if there are so many powerful ninjas in your current bracket in SWB, level up and who knows, the higher bracket might not have that many powerful opponents. Power is not everything. Its only 50%, and the other 50% is your ninjas. I am lucky to get Shisui, and with him, I can beat a 15k higher bp than me.
