exactly. no monk or ninja would stand toe-to-toe with a knight and duke it out. He would go 'metal gear' style and slit his throat or break his neck making no noise.
as for the samurai vs. knight argument, it would all depend on the quality of the katana vs the quality of the knight's plate. and btw, that 40-50 pounds for a full suit of plate (+ shield too?) is a total joke. maybe 'carbon fiber' plate...
