I get what you're saying in a way. Did Eminem really need to step down to answer this diss? No.

But i definitely believe this has helped him in so many ways, if he doesnt answer back you have the current people the thought MGK won before Eminem released anything constantly going on about it.

That wouldn't be to much of a big deal for a lot of rappers but because Eminem was in state where people where judging him and saying that he doesnt have it anymore after Revival. Nobody took him serious and he truly looks like he's lost it if he cant reply back to MGK (who at first glance had a decent ish song/not diss.)

Since doing this diss ive heard nothing but how all of a sudden everyone agrees again that Eminem is one of the best or hell can even rap still.
