The problem with a full ArPen rune page mid though is that a) early lasthitting is an absolute pain in the ass because you will only have around 60 AD and no abilities you can spare to help with it and b) you will get badly zoned by almost all mid- and long-range champions because you have no way to harass them.

Both problems are kind of solvable with later ranks of Fishbones, but you will burn a huge amount of mana and push your lane quite hard for it. These can both be used against you since your opponent is more likely to build mana regeneration (or just be manaless period) so they can win by attrition and/or can force the lane to freeze at a place where you'll be in danger trying to CS.
