Riot, what champions have not turned out the way you intended?
Not so much in the sense of "We didn't intend for Vladimir to be this toxic champion".
Rather, something like "We didn't intend for Ekko to be a tanky jungler".
My thoughts: I definitely think Ekko and Fizz are one of the worst offenders of unintended optimization. Ekko and Fizz were intended to be solo-lane mages, and you see Ekko being played as this jungle tank and Fizz as a solo-lane, auto-attacking bruiser.
What other champions do you guys think fail to fill their intended mold? Rioters, what do you think would be good ideas to remedy the disparity?
