She sucks, weak Pokemon team and dat line "I am an actress with a side-hobby as a Pokemon trainer." Like really?
How about "Hello, my name is Jennifer, I am a full time lawyer and I play Tennis as a side-hobby, like, 2~3 hours a day, you know, and I have 5 Olympic gold medals in tennis btw."
Come on Game Freak, you can do better than that. We all know what it takes to be the best. To be the very best, it not only takes adaptation skill and talent, the most important element of success is hard work. There are plenty of talented people in the world, what distinguish the difference between decent and the very best is the amount of time and practice one puts in. The very best spends countless hours everyday, fighting countless battles, losing a lot of them, learn from the mistakes and get better. Even if Diantha is somehow that ridiculous where what she learns in 1 battle is equal to what other people learn by fighting 1,000 battles, she deserves no respect.
