Unintended StormRazor Reaction With Jhin?

It's already difficult to get my primary ADC role when queuing up for ranked. But when I do, I expect everything to run smoothly and for me to be able to carry as an 11/3 Jhin . I'm responding to an Ahri ulting into mid lane as me and my Gold ELO "teammates" are inevitably sieging down mid lane like we're playing ARAM instead of Ranked. I use three autos real quick, the 1st one is a StormRazor crit (As I had just bought it), the next two standard, and I position to avoid the Ahri Q and expect to quickly use my executing fourth shot to get a kill and save the rest of my team from feeding her even more. But to my surprise, instead of notoriously spinning around and using my fourth shot's crit strike, I do some half-effort step back normal crit. This isn't enough to kill her, so her q comes my way and I'm left gaping at my computer screen, wondering why the heck my champion didn't just use his arguably MOST IMPORTANT AND SUBLIME feature. I recount the shots I took beforehand... One, Two, and Three, yes I should have been on the fourth... I look everywhere, my runes, abilities, even my MS and FPS to see if I'm lagging, but, no dice. Then I see it. Stormrazor is sitting there inconspicuously as an item can be. I read it's passive. Yes, a bonus crit if I haven't auto attacked in a while... So why did I do so little damage with my fourth shot? I respawn and walk to a vacant lane, then I repeat the scenario. I figure it out. Stormrazor's passive (Storm's Edge) replaces Jhin's passive, possibly the most important part of his kit and especially his laning phase. I then begin to think how I could ever make this work, hoping to God that I'm missing to something and Riot hasn't made this new item terrible on Jhin. But alas, there is no happy end to this story. There's just no way for me to time my auto attacks perfectly in unison a teamfight to stop the fourth shot from being cancelled.

"Stormrazor will deal 1.2 more times your my normal autos. This not only applies to your non-4th shot, it also applies to your 4th shot." Which undoubtedly means suicide for those who build it on Jhin, because you still have to reload. Someone explain why Riot specifically released this item with a special condition for Jhin (the attack speed in relation to the CD for the passive), yet this happens. Jhin still isn't in a terrible place for the time being, at least relative to Kalista, but I'd still love to use this item which should be a perfect item on like all the other adc's. [sg-janna]
