In order to keep the conversation afloat let me give you my .2 cents, as I main Ryze.
There are 3 things that, I do believe if addressed, we could get Ryze to be more competitive, more picked and probably improve his winning rate a bit higher.
Ryze still relies a lot on items, still relies a lot on the blue buff to keep him on sustain and can't actually fare too well against most top laners. Now that the newness wore off, every top laner knows how and when to strike Ryze. They keep a little away of the minions, generally on the side, either left and right, and strike once we spent our charges. Because they mostly have gap closers, they just win easily. We just went from having absolutely no farm to have like 24 seconds of farm (we need to have at least 2 stacks to be dangerous and keep 3 spells always up for the combo stack - you use q to farm and all the other 2 and R to the end to become the powerhouse).
However here's what's currently keeping Ryze on the lowest levels of picking:
- No sustain - we have no way to refund on mana - we are reliant on items to give us that - and we are reliant heavily on our active abilities to do anything - which ends up consuming a lot of mana.
- No gap closer/escape alternative - we have nothing that will make us jump walls, skip anywhere, get anyone, nothing. Only our ultimate increases our movement you can be rooted, stunned, etc etc
- All In strategy - Because we can't control stacks, it's an all in strategy... We can't lose the stacks momentum because once their gone, we have no strategy left, nothing to play on. We need to push back. So in every time, in the game - early, mid or late - once we lose stack control, we have to push back, get our stacks back to 3 so we can put it up.
Anyone who knows Ryze know how easy it is to counter him. If Ryze has no mana, it's a Scuttle Crab. If he has no stacks, go in - he can only root you, at best, which will take like 1 second or less to fade off - and you win the fight.
A mediocre riven can either win the trade or just pull off oh so easily. Irelia, maokai, rumble, fiora, tryndamere, etc, any toplaner has both escape mechanisms or highly counters to Ryze. The only rule of thumb to win against Ryze is: stay away from the minions and keep an eye on his stacks. Once you know this, everything else is easy.
I like the mechanism they gave Ryze, as he can farm better now, but if he is caught anywhere else is lane or any other tower, you are toast.
I would love to take Ryze as a jungler, support or even ADC. This is my champ and I just love him so much. Alas I know that's not possible, but I also know that I am very very limited to what I can do. As a Top laner, I can't really roam that much, as I am heavily dependant on the farm to keep myself afloat. I can't gap close so even if I roam, my window of helping out is reserved to large mistakes made by the enemy team member, and I really can't sustain myself as my mana regen/refund is crawling unless I have blue buff.
I really would like to hear from other Ryze players and this is obviously my own (flawed?) perspective of the changes to Ryze.
