Yasuo item build
So I been wondering when do you build Bork over blood thirster or blood thrister over Bork. Also what do I build as my last time when I am ahead? Trinity force, bloodthrister/Bork, ravenous, or semitar???? Since the infinity edge nerfs should i change my runes (I use same runes as bjergsen) and/or consider phantom dancer instead of shiv? Last question is even the game is even or I'm behind should I build a health item like randuina or banshees or build ga as last item??? I know its a lot of questions but any help would be greatly appreciated! Thanks.
