The cure for ryze's uncomfortable situation.
I know this might sound insane but what if they left his Q W E alone and reworked his ult to something that synergizes with his kit. Doesn't have to be something crazy, it could be like a ghost and the movement speed doesn't stack with the actual summoner ghost. maybe make it increased resistances or maybe some type of shield since ryze is a very in your face mage.
This ult makes ryze a good pick in competitive and a horrible pick in low elo because there's no teamwork there. I'm honestly astounded that riot hasn't done anything about this, you can see the pattern here where every champion has some synergy between his ult and abilities but yet this blue man is lacking in that side and he's surprisingly not doing good.
I wish a rioter would respond to this, you are welcome to do so and that would be very lovely ryze mains complain about this and I'd love to see you prove them wrong.
