Can cull get a small buff?
It's like that item that people fooled around with at the start of preseason before they realized it was inferior to doran's blade. After stacking it for most of laning phase, they barely get the cost of the item back when they sell it again. You're better off getting a long sword + 3 pots if you want a better lategame, or a dorans blade if you want a better early game. I see it once every twenty games (being generous here because quite honestly, I can't remember the last time I saw it at all).
is by far a safer bet. Cull MIGHT be better if you're against Nasus or something where you need to push him out of lane, but otherwise, it's just taking an unnecessary risk
