The Soraka and Taric reworks were indirect buffs to assassins
When they got reworked they had their point and click cc removed. Everyone thinks this is healthier for the game cuz "more counterplay", but at the end of the day it means assassins have less point and click hard cc to worry about when they dive your squishies. 99% of assassin abilities in this game are just point+click and are literally impossible to mess up. I feel like supports should have some point and click cc too. I'm not asking you to completely revert Soraka and Taric, but consider giving them back their point and click cc at least. On another note, the exhaust nerf a while back was another indirect buff to assassins and was COMPLETELY unnecessary. Then you add duskblade that lets assassins destroy wards instantly. Supports are supposed to protect the squishies, but you make it harder and harder to to so every patch Riot.
