Ryze Rework Ideas

Okay, I love playing Ryze, but as everyone who has played him for at least 3 games knows, he is extremely over powered. I have a couple thoughts of how to make Ryze play out more balanced. Basically all of the changes are to the passive.

Now takes 6 spell casts to stack (Making it take a bit more time to charge) While Ryze is supercharged all of his abilities have a 25% increased mana cost and do 10% less damage. While he is supercharged rune prison's root is reduced by .05 seconds. Supercharged now lasts for 7 spell casts.

All numbers are not final and are open to change

Let me know what you think!
