40% CDR Ezreal is now super awkward

The changes to Qs CD mean that at max CDR, a consecutive Q will have a 1.2 sec CD. SpellBlade from IBG/TF has a 1.5 sec CD. I found this out the hard way using IBG and noticing that my 2nd Q offered no slow or bonus damage. I never thought I'd say this, but there is a thing as too much CDR on Ezreal. It seems anything over 33% (4.5-4.5*.33-1.5 = 1.515) suffers from this issue.

This is yet another situation where ER is shown to have poor synergy with Ezreal. For one, his Q doesn't crit. so neither the mana return nor the crit. are as useful as one would expect. Of course, you still auto but not quite as much as other ADCs. ER is much more synergistic with nearly every other caster ADC (think Lucian, Corki, Graves). Now, because Ezreal gets a Sheen item to make his poke more potent, he already has 10% CDR and ER caps it to 40% after IE, creating the issue described. You could suggest not to get IE on Ezreal but that makes the whole build seem rather pointless. Why build 40% crit. chance and then fail to get the biggest crit. damage increase item in the game?

Ezreal has needed some buffs or tweaks for a while but I now dislike the latest Q changes and would much rather they buff his W to include an AD scaling or something of the sort. Alternatively, his Q could have a longer CD but some sort of crit. modifier etc. I'm just brainstorming but I shouldn't have to worry about building too much CDR on a champion that seems so suited to it. It's strange enough for me, but just imagine for someone newer. They'll probably think IBG is bugged. Riot needs to really figure out what Ezreal is supposed to do best and how to get him to that state smoothly. I don't want something terrible and lackluster pigeonholed into essentially one build and playstyle like what happened to Kog'Maw.
