What gives more damage on Riven; bloodthirster or black cleaver?
Obviously bloodthirster is the better pick if you are more worried about nuking squishies, but what about against a team with 2 or 3 beefy champions (or at least one heavy duty armor stacker?)
My typical full damage build has always been (not in this order) Ghostblade, Hydra, Maw, Last Whisper, and Bloodthirster. However, I am wondering if it might be better to grab black cleaver over bloodthirster against a heavy tank team. I'd grab it over last whisper, but last whisper is too cheap of a powerspike item to pass up.
