Anybody feel like its harder to get an S on supports after patch 6.15?

As a support main I have 2 level 7 supports and one lvl 6. I never ksed my team (the most kills ive ever had was 5 and i had 35 assists so i guess its fair to get a kill every 7th assust especially if its by accident) I ward a lot (i usually empty my sightstone every 2 minutes) i usually have 2 pinks on me and one on the map and i protect my adc til they're strong enough for me to roam and help the team. I get my oracle and deward a lot with it ans with the sweeper and with pink wards. I heal and shield and speed a lot I used to always get S on my champions but after the patch change i keep getting A+ no matter how good i do

Am i the only one facing this problem?
