A fun Build for WW

start with either or depending on lane opponent. You will build both but start with the one to give you the better sustain then just build pure speed and critical. It might not win you the game per say, but trust me it's fun.

Gives you hp, armor, and move speed Gives you a little magic resist, lifesteal, and a debuff Speed, damage reduction, and crit Speed, crit, and a little magic damage Damage and crit Crit, 30% cooldown, damage, and mana restore

it covers a lot of bases for WW and grants him a ton of speed, lifesteal, and damage. It might not work in every fight, but it's good enough to solo baron with.
