your not alone. The sinnoh saga in the league was way better things were planned, battle weren't rushed, there was strategy. I enjoyed every moment in ash v paul. This league feels rushed just to finish it and start the sun/moon saga. Everything seems rushed, dumb. Even one thing points this out. Ash's noivern. All of ashs pokemon that hatched from eggs didn't rush in growing. They took time to mature, learn moves, get experience in battle. Ash's noivern has little experience (reason I haven't said zero is because of a few fights) this is the reason it gets knocked out so quickly.
Im just think this anime had so much potential but they rushed it and relied too much on geninja.
