It usually is, yes. For obvious reasons, the AD from Youmuu's is helpful, as are the cooldown reduction and armor pen unique passives. The crit chance also helps him hit harder in situations where it's needed most, like trying to race for jungle buffs.

Also, if you have Youmuu's on Yi and get into a teamfight... Drop Highlander (R), Wuju Style (E), and the Youmuu's unique active (Inventory Slot # of Youmuu's). At level 18, those 3 boosts alone should give you, if I'm stacking everything correctly, +100 AD, +130% AS, +60% Movespeed, +15% Crit Chance, +15% CDR, and +20 Armor Penetration. And if you've already got a lot of AD built on Yi.... he will HURT. A LOT. Got him to over 500 AD in a game last night. End build was Youmuu's + 2x Phantom Dancer + 3x Bloodthirster (each BT fully stacked).
