it is still binary, he lives and die with his Q hitting or not.

Yeah another charge for sure reduces that, but its not like something will magically change until a rework.

The notion behind this sort of work is to find solid improvements that players will appreciate, and to do it on a cadence that allows us to deliver them with greater frequency. Some champions definitely need reworks, and we aren't canceling reworks, but these mini-updates exist in the space between full VGU and shifting numbers around, with the hope of making real, honest attempts at solving the sorts of problems that can't be solved with just numbers and generally enhance champions that we feel could use it.

I don't expect Amumu to suddenly dominate Challenger play, but, if we can reduce his 5% winrate skew to 3% after it all shakes out, and help Amumu players feel like they can take their champion higher up the ladder and Diamond players to not feel like their teammate is griefing them by picking Amumu, that's a big win.

If their intention was to make him a good champ diamond+ they might have to go to the drawing board. Amumu is absolutely god tier in iron-gold while still mediocre diamond+. I don't think he is terrible in high elo and I like the direction they are going with him but I have no clue how they are going to solve this massive winrate discrepancy between low and high elo.

It's still early in the patch, but our data has him as 53.8% in average play (silver-ish) and 50.6% in skilled play (plat-diamond). If this holds—fingers crossed—it means the 4.5% winrate discrepancy last patch has been reduced to barely 3%. Getting it to 0% was never the plan, because I have no idea how we would manage that while still keeping Amumu Amumu. MMR skew can be quite hard to achieve while also respecting the existing playerbase by not making dramatic changes to the things they enjoy. I'm also hoping that, winrate aside, the increased early-game power is a sufficient qualitative improvement to his usefulness that players further up the ladder will be notably happier to see an Amumu on their team than previously.

This does mean he's toeing the line for a nerf based on his average winrate, which is fine. The change was uncertain enough that there was always high change that small followup tuning would be needed.
