I also think it's useless to ask for this kind of change, since there are many formations out there used by many people (with water, fire, wind and lightning main) that are strong enough to push someone to ask for their power reduction.

There are always strategies to beat a team, like many already said, so we just have to use our brain to counter them, and of course there is no team who can beat anyone, you will always face someone stronger and lose, unless you really have a lot of money to spend in the game, then you can win even with Konohamaru, Obito boy and Kakashi shonen!
