MF's Q wasn't really the issue but OK
MF's Q was easily avoidable (disregarding the terrible physics of certain shots) in lane. The entire purpose of the ability is strictly for lane. It provides a tremendous amount of zone and power for those who dare to stand behind minions. But....it really wasn't the problem. In the patch 7.5 post, Riot says
>"For Miss Fortunes willing to give crit another chance, however, late-game Q’s will reliably knock the teeth out of squishies"
This really doesn't do anything for MF lethality build besides hindering (some) power. We all know what happens in the "late game", approximately 16 minutes in, MF appears with Youmoos + Duskblade + DFT and ults the entire team. At that point no one really has armor or a GA so it is a easy trade for MF.
