Riot, are you gonna do something about this abomination??

Sitting at >52% win rate with 20% pick rate. Point-click shields, slows and aoe heal ult. Free movement speed buff as a bonus. You nerfed Sona to the ground and now this shit became the most annoying support to play against. Why is she allowed to be in such powerful state given the fact that even a 4-year old can play decent Janna?
