I do not usually build lethality with Miss Fortune, but I have noticed in this guide and many other guides that they do focus on lethality, I will see how will that work out for me in the next games. I usually do my own build, but trying something new is fun. So, thank you :>

Hey Nateshark,
you're heading says it, your guide is short but basically contains all the important things like runes, items and match ups and counters. Well and of course Pros and Cons! Sorry, almost forgot about those.
Personally, I'd prefer if you could add some more match ups and counters. Like Lucian, Jhin, Twitch, Braum and so on. You don't have to list up all possible ones since that would be too much to ask, but it'd be nice to add at least all the common ones.
But you're on a good path. :]
