I just really want to know - what do you guys max on her? I really think that maxing e first is the way to go, not for the poke - but for the very intense aoe slow it gives, allowing u to ult better or kite with w. Thing is I see many maxing q which i understand is a great poke esp for laning phase, but is it really better for first max?
I would suggest checking out 
's Champion.gg page. Might be a good start since its information is taken from Platinum+ games.
Hi, diamond Miss Fortune main here. It's situational what you max but generally you want to establish lane dominance and get a lead going to close the game out quickly so maxing Q is usually your best bet. Against a team comp like Warwick + Singed + Braum, you could also gain more out of maxing E first due to the slow increasing your self peel. W is what you max second in all circumstances. So basically, max E if you need self peel and kiting, max Q if you have potential to snowball a lead and get fed then close the game out early. Max W second every scenario. Hope it helps <3
Try out my MF build.
Ghost blade, death's dance, swifity boots are core. You can do black cleaver right after ghostblade as well which i do in most of my games. You can also go tanky with a Hex drinker or you can try the new duskblade I hear people really like on her these days. I generally eventually pick up last whisper when I see enough armor stacking where I feel I need it. You can also go IE and phantom dancer if you want more of a sustain damage build but you have to leave out the black cleaver and maw from the build. Remember your ult can crit so crit even helps your ult. Generally though I go AD caster Miss Fortune.
Max Q first, then E. Go deathfire mastery and armor pen reds.
Deathfire mastery will make your ult hit like a freight train along with all your other spells doing a bit of extra damage.
