Context on Jayce nerfs
Riot, why Jayce is being left out from the postponing of the nerfs? He builds the same lethality items as Talon and Quinn and takes the same masteries too, he will be affected the same way as them.
His winrate also starts dropping after 30 minutes where he goes to 45% and in 40+ games goes on 43%. Why do you think Jayce needs nerfs on his last levels of Cannon Q and a mana cost increase while Talon and Quinn nerfs can be delayed?
