At least he became viable. They actually worked for the better. And I said "despite initial problems" - it wasn't an on-going thing like with Cass or Morde, complaints generally just halted. I actually remember people saying that he didn't need another rework after the first one - "He's fine now. We're fine with him. Don't do it again when you basically solved his issues." And then they did (for whatever reason) and everybody got pissy looking at the numbers because it looked like a nerf - then he turns into one of the best duelists in the game, and again, quiet. Because Skarner was still, at his base, Skarner.
Morde's not Morde. He needs to be redone again, and this time make him who he is.
And please remember that if they completely removed MF's AP scalings for more AD scaling, you'd have a fair amount of people pissed about that, too. Skarner's rework wasn't bad - it was different, and people were mad beforehand simply because it was different. Morde's has been accepted by basically every single player - main or not - to be not only more toxic than he was before but an utter shitfest of mediocrity in terms of engagement.
