For an on-hit/attack speed build. Do people use armor pen or magic pen? I'm currently using magic pen, but I'm thinking of switching to armor pen because I can't really see 9 magic pen making any significant differences, and the armor pen would help slightly with last hitting (which i suck at) and early game harass.
