During season 3/preseason 4, I've been seeing AD casters who buy a brutalizer face a dilemma on what item to upgrade it into, Youmuu's Ghostblade item.png Youmuu's Ghostblade or The Black Cleaver item.png The Black Cleaver.

Sometimes, I think for sure a champion should buy one item or another. For instance, Master Yi Swordboots has his signature Alpha Strike.png Dash Move, but is more of an autoattack reliant melee carry should buy the Youmuu's Ghostblade item.png Supa Speed Blade, especially since he can crit with the Q.

In contrast, Garen DEMACIAAA!!! or Riven Ms Toplane Faceroll should buy The Black Cleaver item.png The Black Cleaver because Judgment.png Beyblade and Broken Wings.png Broken Move quickly stack armor shred.

Yet even though Garen and Riven aren't autoattack reliant, I've seen people buy Youmuu's Ghostblade item.png Youmuu's on them.  Does the extra mobility from the active outweigh the extra health and armor shred from The Black Cleaver item.png Lucian Killer?
