Umm i don`t know if this is just my opinion but could you consider nerfing MF. I mean goind lethality she can one shot the champs around 2k Hp , and going like hyoer carry she is dealing enormous dmg as well ? so my question is if someone else thinks that this is a little too OP or to advise me something to counter her please comment :)
she is indeed op. but i don't think she needs nerfed. not as much as the range of caitlyns kit does.
To beat a MF
#1 Counter pick her if possible. You see them going MF you go 
or you get a support that can stop her ult or go 
who can quickly get out of the ult
#2 EARLY GAME: don't stand behind minions that are low, she gets double damage on her Q if it kills the first unit it hits. I can do almost 260-300 damage if I can do it right
#3 Mid-late game: Focus her.... Wait to engage until she ults, if you have someone on your team that can disrupt it then make sure they do so quickly. MF's ult is VERY easy to stop. Any kind of a stun, knock-up, or push/pull will stop it. Like 
's Spinning axe moving thing.
So to summarize, disrupt her, counter pick her, don't stand behind minions early game OOOH AND if she builds full lethality (like I do :P) then she'll be weaker during the Early game.
