I don't know how people expect the progress you make to be balanced. A ninja that is from the beginning of naruto stories cannot and will never be as strong as a ninja that came in later in the story. Most of my opponents who got tobi always loose to me and I only paid 4$ so far to get Gaara. Don't use the lack of your strategy as an excuse for a character nerf but I do have to agree that there are things that should be balanced. For example the main characters are not balanced at all throughout the game. Early- mid- and lategame. Early game the earth char is pretty strong but has a huge falloff in midgame but catches up in lategame again which is not yet included in our version. Those are things I would like to see to get balanced and not nerf one single ninja.
