Nashor's Tooth, does it need a little love?

Nashor's Tooth seems like its an interesting item that could be used more often, but isn't. Looks like it could use some QoL improvements from riot.

50% AS - Not bad, helps with clearing waves without skills, trading, and taking down turrets. However not a lot of champs need AP and AS. 60 AP - Not terrible, but not good for the overall price and a little low. 20% CDR - not awful, a nice plus but it doesn't justify the item either. On Hit Passive damage bonus - It is helped by the stats of the item. It seems like more champs could use this than do, but a lot don't. FWIW, I put this on Orianna in poro map and got a Penta out of it from mostly AAing, might have had or was working on a hurricane as well.

2920 GP cost - IMO this seems like its the deal breaker for me. LB is only a 100gp more and gives you more AP and move speed. Rylai's is 20gp cheaper and gives you health, more AP, and soft CC. Liandry's is 20 cheaper and while it does give you less AP, it gives you health, magic pen, and DoT. Rabadon's is 380gp more but gives you a lot of raw AP. DFG is 180gp more and gives you a lot more AP, a little less CDR, and that active.

As far as gameplay, it seems like it'd be a great item during laning (unfortunately cost) that will help AP champs clear without using mana and gives them something to fall back on later if their mana is low.

Am I wrong, is this item fine? Also who have you all had luck using it with?
