Dr. Mundo is one of the weakest champions out there
Due the buffs to Mortal Reminder, he sits at 52nd place out of 61 possible top laners in the game https://www.champion.gg/champion/DrMundo.
If we exclude those who are both played mid and top, he becomes the the worst tank/bruiser in the game. Could he get some buff that prevent people from lowering his regeneration, at least from ultimate? I mean it's his signature ability, and there are plenty of viable counters to it right now. If Fiora/Zed/Trundle were made so that their respective ults cannot be countered in any shape of form, why are they so many possible counters to Dr. Mundo and his ultimate?
