Champions

[Kaden]

Don't sell Ghostblade. It's just too good on Yi. Build survivability in the mid-late game when you're teamfighting more and teams can just focus you down. Warmog's is not an uncommon item on Yi. With Meditate and lifesteal, all he needs to be able to do is soak damage, so pure HP is a perfectly fine stat (makes Atma's better on him, too, which is nice because that item has great stats for a champ like Yi).

Multiple PDs is cute, but never necessary. He gets a ton of Attack Speed and Movespeed for free, so itemize the stuff he's lacking. Don't buy CDR Boots, just be smart about activating Highlander. Merc Treads are crazy good on him, since the only thing that stops Yi is hard CC (and even then...).

If you're going to rush a GP/10 item, you're better off having it be Philo Stone or HoG and just sitting on it for most of the game, eventually turning it into Shurelia's or Randuin's (both decent options to help with survivability instead of Warmog's). Avarice blade is a bad item who's only redeeming quality is GP/10, but putting it into Ghostblade as soon as possible removes that quality. So it's just a bad item.

You clearly have an idea of what items Yi wants. Just give some priority to survivability and I think you're fine.
