User blog comment:Emptylord/Custom Champion - Muzen'Khan the Wings of the Abyss/@comment-7709681-20140913155355/@comment-3974211-20140913160829

Yeah, he's got a bit of a role-identity crisis. I haven't touched on Muzen'Khan in a few months, but I've been overhauling all my custom champions and I decided to publish this at let the blogosphere discuss his issues rather than letting him fester. He's transitioned between ranged support, melee support, AP fighter, AD fighter and Assasin, but his kit has largely remained unchanged for quite a while - with only scalings and such rearranged. I think at one point it was wanted for him to be a functional AD top OR AP support, similar to how Kog'Maw is a functional mage OR marksmen. Anyway, my original point: looking at him from the perspective of someone who hasn't looked at him for months, I'm not getting the sense that he's lost the fragility that was intended to make him desirable to duo-lane — i.e. he's suppose to have a lot of tools to create mass terror, but struggle to hold his own.

I didn't follow Gnar's Q&A, so I don't know if he had that ability. Muzen'Khan long predates any inkling of Gnar, so similarities would be coincidental.
