Hihi, Captain iglo949 here.
This is my first real guide on mobafire, and i hope you like it!
I am Platinum I at the moment and trying slowly to get Diamond, but school is holding me back right now.
This way of playing Miss fortune is a mix of the insight of the pros and my own tastes and preferences. The bully style is something the pros do less of because it is kinda risky, but the most fun in my opinion.

Have fun playing Miss Fortune, and enjoy my view on the game!

With this build and ability sequence there are two things really strong about Miss Fortune. Her R brings Massive damage in post-Lvl 6 fights while her Q applies a lot of pressure in lane. But her Q needs some practice and has a couple of nice aspects to it.

The first thing to do in lane is push. AS YOU SHOULD ALWAYS do is push to Lvl 2, and this is especially relevant on Miss Fortune, because your early damage is really high. When you reach Lvl 2 before you oppenent does you need to put a point in E as fast as possible and engage like a madman together with you support, because that is a fight you cannot possibly lose if the opponents are not Lvl 2 yet.
When you kill you opponent on Lvl 2 you should push the lane to the enemy turret and go back. If you can get a BF-Sword that's the best thing ever, but a Caulfields Warhammer or two Longswords are fine too. Even Longsword + Boost of Speed is an ok back, considering you opponent didn't have the chance to push the lane.

If you return to lane or you didnt go back at all the bullying can truely begin.
The trick sounds simple but it requires some practice. You kill the enemy melee minions without using your abilities, but think of love tap to push faster. When you have killed the melee minions you try to line up your Q through the opponent's caster minions. If you can kill the minion with your Q and hit you opponent with it you deal ~200 DMG on lvl 2, which is around 40% of the enemy ADC's life total at those levels. If you do this properly you force the enemy to make a decision: Either they walk into your Q range and get poked or they miss a lot of cs. Either way you come out on top.

If you repeat this pattern you will push towards the enemy turret, so make sure you have proper vision of the enemy jungler.

Once you completely dumpstered you opponents in lane your time to really shine has come. If your team groups and fights over an objective (turrets, inhibs, Dragon, Baron Nashor, Red & Blue buff, etc.) you stay really far back. you wait for the enemies to engage or for your team to pull the trigger and then you unleash your wrath over the opponent's health bar. You try to stand on a safe spot and ult their whole team. You get a Pentakill and you can queue into your next game and enjoy the free Lp. If you do not get an Instant Pentakill you should try to stay safe and keep your DPS as high as possible. That means autoattackting the enemy, walking back a little bit until you can attack again and repeating this over and over. If you think you are dead for certain you should put out the most damage possible even though if it results in you dying a little bit sooner, so your team can win the fight even when you are dead. Because the job of an ADC is to deal as much DMG as possible.

- MF's Q is an autoattack reset. That means that you have to use it immediately afer an auto attack to maximize your damage.

- When you are attacking a turret with your W active, be sure to attack the tower, then attack a minion, and so on. This way you keep refreshing your passive

- Your W is also a Strut reset, so if you are runnig away or chasing an oppontent remember to use it as a small movement speed boost if you need to.

Just use these runes. End of story. These runes bring the perfect balance between offense and defense in lane. The 1% crit is a favorite of mine, i just love myself a good Lvl 2 crit on the opponent's face.

This are the masteries I use. I use these because i think Thunderlords Decree has significantly more impact than Deathfire Touch in my opinion. Just the standard Adc masteries, nothing special, with Thunderlord's Decree.
