It's odd because Jayce, for all intents and purposes, is a transforming champion that serves a similar role in similar fashion: toplane anti-bruiser with a pokey ranged form and a big-damage all-in form that capitalizes on %health damage to punish lack of resistances.

I wouldn't be surprised if Jayce lost his passive resistances.
