Why do I feel uneasy playing this game? I don't know how to properly level up my characters!

This game drives me insane. Leveling up magic without using the 'cheat' is almost impossible. I can't even play through this game without feeling that I am doing something wrong.

What do you recommend for weapons for each character?

How did YOU do it?

Did you bother leveling up magic?

Did you use the 'cheat', where you cancel continuously until you level up? I feel bad using this, especially because the last person in your party cannot benefit from it.
