You are still going to want to go for the Maw and Randuin's combo for battle stats. Passive on Maw just give so much AD, it's your biggest item. And the health + slows on enemy auto attacks and active on RO makes it quite the item to get on a Tank Yi.

If you need any more defenses then this I'd say swap out BotRK for SV.

As for top lane, I supose you could swap out FF for Wits End? I wouldn't know, I don't play Yi there.
