She also gets mimic at level 2 which I think is too early.
I was thinking about this too. I don't play in lower leagues, but it might be devastating, especially with Tofu.
You technically don't need a mimic for that. If you spend a year learning/working on something, you should have some proficiency at it at the end of the year.
I am glad that you picked up on that ;) This is exactly the case - where while maybe not an expert after a year, the chance to be pretty good at something is high, so why don't we do it?
I think the answer is pretty simple. Time and Money. We don't have enough time. Growing up we realize that we can't do everything that we want. A lot of people pour a lot of time and effort in their work even if it isn't what they want to do. Parents sacrifice their time to take care of their children.
I want to do a lot of things like play the guitar/piano, learn Japanese, get better at sports, etc. But not only do I not have a lot of time to learn and do all of them, but they also won't help me get more money for basic needs.
