Even the skill & position training features being gambling is a joke

Is this game all about gambling? couldn't they just make these trainers harder to obtain instead of making us waste them getting the same unwanted skills and positions all over again? Or Konami just thinks that's okay to give my strikers the Sliding Tackle and Blocker skills, or to give me the position my player already plays like 10 times in a row. Good job Konami, what a nice multi-billionaire company!
