Turn Nashor's tooth into strictly ASAP/on-hit item?
With new sources of CDR for AP champions, namely Protobelt, Zhonya's and Abyssal, Nashor's users might have hard time incorporating those items into their build, i.e. while 20% CDR on 
or 
is nice, they have no real reason to go above that and it becomes a waste. And, as Zhonya is still only armor item for AP champions, and because 
and 
still exist, sometimes you must buy it, want it or not.
Also, this would be a nerf for Kayle who makes best use of CDR of all Nashor users, and she is kind of dominant so that's fine.
I would than say that removing, or reducing CDR on Nashor's soon after 6.9 patch would be reasonable. Simplest way would be to bring back blasting wand back into it's build path to reduce CDR to 10% and make it cheaper to compensate:
= 
+ 
+ 650
but honestly I don't think this item should be so cheap or it would be too snowbally, so maybe it should be given something else for that 300 of gold value it would lose, like say bringing AS up to 60% so that Azir has more actual reason to finish the item? IDK it is Rito who is supposed to do balancing, they take money for it kappa, I only wanted to point out possible issue.
