Natsu ate the stink fire without realizing what it was and felt the negative effect right away.

I see, actually, the Oracion Seis arc is the one I'm least versed with so I apologize.

I was just saying that they all had their weaknesses, not that they didn't (and I agree, that thing about Sado's power kinda pissed me off too with the change). No doubt Fairy Tail would be an overall incredible series whatever happened here but I still think that the 'eating' is something that can't be explained rationally and satisfactorily, even if it can be at all.
