Knight's Vow passive
UNIQUE Passive: If your Partner is nearby, heal for 12% of the damage your Partner deals to champions and redirect 12% of the damage your partner takes from champions to you as true damage (healing and damage redirection are reduced by 50% if you are ranged).
I liked this at first, but I am kind of doubting the True damage now. It means that if your adc likes to eat lead, you will be receiving more damage for the 12% part than he is and if he isn't attacking back, you're just going to be killed quicker than you would normally be. This item makes supporting a lot more difficult and I think it might cause problems in lower elo.
