Summon Rates

Im honestly so upset at this game right now. Ive been playing for weeks to farm up stones just for one banner, and finally I get a "Bye Guys" screen animation (which signifies a guaranteed SSR) and I get this horrible strength Teen Trunks. Its ability is so bad, it only increases 25% attack to strength only characters. I am so infuriated right now and at this point almost threw my phone on the ground and locked myself in a room because of my uncontrollable rage I was feeling. The summon rates are so low, most characters have a less than 1% rate! This game gives you these low rates so you can waste dragon stones and pay money for more stones. The game is outdated and isnt even close to being up to date with the Japanese version; in fact its, 6 months behind. The game play is super slow, each animation takes forever and its all just absurd. I am so frustrated right now and honestly words cant even describe how I feel right now. Please fix this game. I would play this more if the rates werent so low. Its honestly ridiculous and I am just absolutely fed up with it.
