Miss Fortune Nerf

I believe miss fortune should have a nerf. Not her whole kit but rather on ability. Her ultimate. Some people may say "No she does not" but in my opinion she does. Ok first off, yes her ult is powerful if positioned right. But, here is where it is very dumb. Her ult does so much damage as most peopel know, but its scaling is why, I believe they should take does the scaling by quite a bit up until level 3 ult, but at least keep the scaling viable. Every MF I have played against. even unfed shreds through the tankiest mofos in league. We had a rammus with 500 damn armor and she ults, boom dead in seconds. Of course if left unfed it does little to no damage, until a little later in the game. I honestly believe if there were to be a nerf it should be a minor one just reducing some ult damage come late game by a decent amount. Most adc's have their weak spots, such as pulling her out of her ult with cc, or how ashe requires more autos to do tons of damage with her q, and if she fails she will most likely get deleted. Although adcs are suppose to shred tanks, I just think its a little busted that her ult does that much damage. Of course its in an adc's nature to do so, but in some cases its just plain busted. Lets take jhin, his autos do tons of damage, come to the last shot he can delete people very easily, only thing holding him back from being "Busted" is is sow attack speed and reload speed, as with mf its her being an adc and being squishy and how once you cc her she is essentially done for unless someone can back her up. This sounds very stupid in many ways, complaining about an adc's ability to do tons of damage, but her ult should be tweaked to the point where its somewhat balanced, I mean yes its balanced a little now, but its also a little unbalanced as well. I would like to here opinions on this, and not extremely negative ones but rather decent ones that aren't toxic. :)
