This is why I liked my Bleach RP.

Everyone was -equal- to start out with, but the numbers in their different stuff was different, so they all specialized in something. It wouldn't work here without a pretty big overhaul of pretty much every character. 

But essentially, it was broken down into, let's use two characters, A and B.

a) 

Zanjutsu - 6
Kido - 3
Reiatsu - 5
Hakudo - 6
Shunpo - 9
Intelligence - 5

B) 

Zanjutsu - 5
Kido - 6
Reiatsu - 5
Hakudo - 3
Shunpo - 6
Intelligence - 9

---

Both are essentially as strong as each other, but have different specialties to make the fight interesting. It worked wonders in Bleach, to avoid things like one character is as physically strong as another, without having to do as much training and things like that.
