Guys... stop telling plat+ players to 'git gud' "because MF is immobile".
You, as an individual, will not notice a 4% increase in the amount of times MF has beaten you, simply because NO player's individual games can produce and adequate sample size.
As for the issue, yes she is flourishing right now. We have an early-game adc here, whose early-game success is amplified by runes, whose poke is amplified by runes, and who can make exceptional use of Duskblade, a problem item. I would prefer Riot approached this from the lethality and snowball aspects, however, as they tend to be a problem on many champions.
