Give more snowball power to supports and less to ADC, and nerf ardent censer
As support main i hate it when i have to support adc that can't farm, somehow get him to 8/2, than ward so he can farm in bot lane safely, but he decides to go mid lane for some reason, builds 1st item bloodthurst on ezreal and gets to 8/12, while enemy twich farmed up and can destroy our team with 1 good ult.
I also hate it when our full team is good, except for adc, than enemy adc can just destroy us if our assassin can't kill him becouse of good positioning of enemy adc.
Give supports more "solo carry" options, so if you are stuck with bad team, you can still win.
Ardent censer buffs ADCs even more, and makes your chanses with bad adc even lower.
Sorry for bad english :)
