Lets Talk about Miss Fortune's W
It needs to be stronger. I don't mean the numbers need to go up or better items synergy, it just needs to be more robust. ANY damage taken will take off MS from her. It can be really frustrating when moving towards or away from an enemy only to have a stray minion auto knock off 70 ms from her kit with no way of getting it back until you're in attack range. With more and more champs being mobile MF not having any escape/gap close really punishes the smallest mistakes and making her W passive more robust may help combat this.
Here's an example: https://i.imgur.com/nllbIx0.gifv you can imagine how frustrating it would be if you saw an enemy come down bot lane, then bail only to be slowed by a minion auto.
and you want her to get an even better version of them ?
