Shaco and magic pen.
Why does Ap Shaco have to build lethality and/or armor pen to deal damage on his E? Why can't he have his E magic damage so he can build magic pen and make it viable instead of building magic pen for some extra box and item damage, it doesn't make sense. He should have some form of damage as Ap Shaco (His E) and some form of damage as Ad Shaco (His passive, Auto's and Q). His Q has pointless Ap scalings because you need lethality/armor pen to deal damage, his passive has pointless Ap scalings, needs lethality/armor pen to deal damage, his E has pointless Ap scalings AND Ad scalings because the ratio's are so low... and also you need lethality/armor pen to deal damage..
be converted to physical damage champ.
