I am an avid Yasuo player, but I truly hate how the BotRK first item feels. Yasuo wants Lifesteal, Attack Speed, Attack Damage, and Crit. Sadly no item gives all four of these anymore, but BotRK gives all but Crit, which seems like it could be good but massivly delays your IE 100% crit power spike.
This build fixes the problem by building a Vampiric Sceptor before PD, which gives you sustain and AD. Sceptor + PD also only costs 250 more Gold than BotRK and you get Ghosting and Movespeed, which makes dodging easier.
It also, damage wise, outperforms BotRK if the enemies don't have much health early game duo to more Qs and more AAs since you have 50% crit with just PD.

Comment what you think of the Build, I find it feels better throughout the entire game and that feeling is also Mathmatically backed for medium sized trades (not single Q pokes)
