I strongly encourage everyone to take a moment to watch Phreak's patch breakdown and how he explained his thought process and motivation behind the huge Yuumi nerfs.
Video link (to the specific timestamp).
I had no idea she had such good base stats, and when Phreak went on to explain that she can out-trade a Draven Q at level 1, my mind was boggled. He also goes on to explain that Pro Play Yuumi's were winning lane, and so he specifically wanted to target that.
It's also very interesting that he is completely honest and acknowledges that Yuumi is not meant to teach the fundamentals of Support, and basically confirms what most of the community has said, in that Yuumi is a champion designed for a player required to do less. That might upset the Yuumi mains, but Phreak straight up identifies that Yuumi players do not need to learn positioning as an Enchanter.
He also addresses that the core nerfs (to the base stats) "will not nerf your friend first-timing Yuumi. They will affect Pro Play." He humorously references the Reddit main thread and that he was amused at all the top comments.
"I want Pros to stop playing her, and I want you to stop banning her."
