Seeing as ryze was pretty much a counter to any non-ranged top laner by have 3 lockon skills I think this was needed. They gave him a clear buff to his passive and ult passive increasing his power a lot. The only thing is you now need to be able to hit a skillshot to use him. On the contrary the Q being a skillshot is actually better for him with his new passive. He can charge up his passive by just pressing Q randomly like vlad does with E. Also I think riot is really trying to change the game a lot. Many point and click mages got good buffs, while making them more difficult to use. Changing zileans bombs to skillshots but making them stun if double bombing, changing veigars Q to a skillshot, but allowing it to hit multiple targets so you can farm and poke at the same time, and now making ryzes Q a skillshot, but giving him a passive that needs to be charged up. All three champions clearly had those skills buffed, but the point and click to win aspect was taken away.
