The fact that NIN - SAM is one of the best combo only means that or NIN is broken, SAM is broken or both are broken.
It was already said by Yoshi himself that they purposely overtuned SAM so people could use it more.
So yes, SAM is broken, no matter what people try to say to justify it.
There's no utility in the game, save Balance, that can add up to 500+ DPS over a fight.
