Is Spear of Shojin Too Good?

I really can't say I understand how Spear of Shojin has avoided nerfs for so long, but it has. Now I don't think it's super broken like pre-nerf Ardent Censer or anything like that, but I do think it's currently too strong. Specifically, I think it's too good at everything, and it can turn some champions into absolute monsters. Riven especially, and I suspect Spear of Shojin is a big part of why she's currently top tier.

I don't think it needs a major nerf, and I think on those champs and champs like them it's meant to synergize well, but I think it works too well on a lot of champions, and I think its current state is a big part of why Riven is top tier. The main reason being its CDR.

Compare SoS to , which for a long time has been the quintissential all-rounder item for top laners. Both of them give 20% CDR, but then Spear of Shojin also gives a whole 50% attack speed upon ulting, and your basic attacks after that reduce your non-ultimate cooldowns. Correct me if I'm wrong, but this means it effectively grants the most CDR of any item in the game when its passive is meant to synergize with basic attack champions.

Therefore, I suggest a simple but important nerf, that being reduce its CDR to 15 or 10%. As compensation its gold cost could be reduced a bit, maybe by 50 or 100, but I do think this would put the item in a more balanced place. I should make it clear I didn't make this post because I got stomped by someone using it or something dumb like that, I play both Irelia and Fiora, I really just think it's too good at the moment.
