Jayce little buff

I think it would be great if we show some love to Jayce. We all know that this champion is pretty mana hungry in early game and kinda hard to survive or be as useful as others champions in late game, because he doesn't scale that well. So, what I want to suggest is: -whenever he kill minions in melee form he can get some mana -when he use E in melee form, if he knock the enemy in a wall, maybe the enemy can get stunned for 1 second, for example or we can make his E like Lee's ult, I mean if he knocks an enemy to another enemy, the 2nd enemy will receive some damage. I really appreciate if you leave in comments some opinions or suggestions for Jayce. Peace and love <3
