Ryze´s ult

Hi guys and girls, before I say anything else, thank you for reading my post. Soo, I have been a main ryze since the lastest rework came out, and I have found myself pretty comfortable with the champion. Anyhow, he has a problem, and is a big one, the same one that champions like kalista, azir and others have confronted. They are overpowered in competitive but weak in solo Q. I believe I have a solution for this. My belief is that it is nothing but the ultimate what makes ryze a difficult to balance champion. My opinion is that it should be eliminated, it is an extremely inconsistent hability. With a huge, extremely diffucult to use potential. My idea for ryze ultimate, and I apologise if someone has already suggested this, is an ult that consist of a passive and a active. The active would give ryze a very small buff, maybe more resistance, maybe spellvamp, but in a very small quantity. The passive however, is what makes the ult really interesting. My idea is that it allows ryze to get extra cdr. IT DOES NOT GIVE HIM CDR, but only allows him to buy over the cap that we have now. This way, in my opinion, riot could be able to work around his damage and be able to balance him more effectively in the future. Thank you for reading this and leave your thoughs in the comments.

Have a good day on the Rift.
