The attack speed steriod and AP ratio that is tagged along with it makes on-hit Miss Fortune a potential champion. Howeverm in reality, that concept is rather poor on her.

This is mostly due to the fact that both the base damage and the AP ratio on her Impure shots is really bad. Comparing her to the more ideal On-hit champion, Teemo. At rank 5 of Teemo's E, it automatically deals 50 + .3 AP of damage to the target instantly. Miss Fortune will need to have full stacks [AKA 4 auto-attacks] on the target to deal only slightly better damage at 56 + .2 AP ratio. And that's at a .1 difference of AP damage is easily remedied for Teemo. This doesn't include the fact that Teemo's poison is an DoT, and thus does even more damage to the target than Miss Fortune could ever do.
