Not to mention Ninjas throw Kunai (DEX based), and use hand signs (DEX) to use various Ninjutsu. DEX being their primary stat is pretty much an obvious guess to many.

Hand signs can also be Int based, using magic as chi energy, like Monk did with his auras in 1.0 (active auras consumed MP over time)
