Idea for Ryze Change which is still using current patch ideas

So at the current time, Ryze's limit during his passive is 5 spells which will reduce the cooldowns of other spells. The passive last for 2.5-5 sec in duration (The more levels of q you have, the more time you have with the passive cooldown reduction). The issue for me is, I need the passive to be reset SOONER. For example, if I am maxing my q, it means that my passive lasts for 5 whole seconds. IN THAT 5 sec, I STILL have the restrictions of 5 spells. So why would anyone max their q ever? There's literally no incentive. I can cast 5 spells just as easily in 2.5 sec. The difference is the more I level my q, the longer I have to wait to activate my passive again.

Here's my suggestion,

1. You want to create windows of counterplay to Ryze. Keep the current passive with a single change: DO NOT allow his passives duration to increase. This way, there is a similarity to old Ryze simultaneously, Ryze would have a window of weakness.

I'm not saying it has to be 2 sec or 2.5 sec, I'm saying give it a set time. Just keep in mind that it should be low enough that he can spam a relatively good amount for dmg.
