Yea I don't think the day 1 "weak" consensus will age well, they usually don't. This one's going to take some time for people to learn as it is so far departed from what people know how to play.
I'm not on the balance or design team but after playing with and against Yuumi a few times and seeing just how differently people are playing her after a few days, I expect some of those hotfix buffs to be reverted sooner rather than later.
