Want to know how to nerf Azir without having to actually nerf Azir?

Fix Nashor's Tooth's gold efficiency.

---

Nashor's Tooth is 139.94% gold efficient.

Even though Azir's main use of Nashor's does not include the on-hit passive at all, it remains 117% gold efficient on him. Considering its a rush, though, he DOES make use of that passive for last hitting while using less mana.

That's pretty absurd, and I'm pretty sure it stems from how absurd used to be. 50% attack speed, 10% CDR for a pretty low price.

Riot went and fixed Stinger, but didn't re-adjust Nashor's as well.

I feel like every pre-season EVERY SINGLE item should be looked into, whether its reworking (completely changing), rebalancing (adjusting), or revamping (changing components+relevant stats) them.

No, this doesn't mean that every item needs to be changed each season, but they should all be generally in line with each other, and at the moment there are blatant outliers at the top and bottom as far as use, and some are extremely out-of-line as far as gold efficiency:

(top end) (considering its counter-itemization vs sustain; put GW on another item or lower its gold efficiency)

(bottom end) .

Did I mention how wasn't nearly cost-efficient enough to warrant starting? There is always a better choice.
