Ninja is weak, like very weak.

I was going to say..
I've seen nothing showing that NIN is behind any tank.
I think NIN does need a buff, but I honestly don't think NIN is 30% behind the other melee DPS.

pDPS is the only think that matters though. /s

They are using 30% (27%) because they are ignoring rDPS.
