@Amrodkun I just realized i missed out the ramp up time!!!!Thanks for pointing out, i will change it soon and what you said is perfectly reasonable, thanks.

Excelent guide, I love how detailed it's about many situations, but there's a point I don't like that much, it's about Last Whisper vs Black Cleaver, to some persons this isn't that important but for min/maxers it can be like a tinny rock in your shoes. You need to factor in that BC has a ramp up time, it doesn't ignore 25% armor since first shot, while in most skirmishes you will be auto attacking non-stop and eventually you will have it up 100% on your target, many times, mostly on equally compared skill levels of teams, you don't have much up time on targets, you'll need to be reposition and switch targets as they come for you (kiting), and this is where LW outshines BC since it's 35% since since first shot. I think a more appropiate comparison would be using final hp after short sessions of auto attacks, not really armor.

Thanks for liking my guide, appreciated it! My item build is based on Chaox guide, i won't take any credit for it, i am just elaborating it.

MF can beat pretty much any AD Carry in lane when played correctly, the diffculty is just a gauge of how easy/hard to win against when compared to other AD, like you won't want to eat Graves Buckshot in your own face, hurts like hell. Moreover this guide was written when Grave was OP before it was toned down, so i got to update this guide within the next few day especially with the new MF buff recently!

@lightone
The reason you want to max double up first is because of its poking ability, not forgetting it resets your auto attack. Make it rain is a bad choice to max first because
-It doesn't gives much except for the slow
-It burns more mana
-Might push your lane unknowingly
Impure shot is definitely MF trademark, but i feel that maxing first doesn't really give much except for extra 20% atk spd and few more magic damage when compared to double up. Without double up, you will lose lots of trading when forced by opponent.

It's a real shame this guide isn't featured. This is easily the best MF guide on this site. I have tried so many MF builds (even hybrid) and this one is easily the best. Although I do have some areas I disagree with. You rate graves as a hard lane, when it's actually quite the opposite. http://www.championselect.net/champ/Miss-Fortune MF is actually quite strong against Graves, and that is the sole reason I bought her in the 1st place. Otherwise this is an amazing guide

It's strange to me that so many value double up, why max it first?
First of all you want to kill to snowball, but double up is harassing ability, not killing and it make diference, in hot pursuit it is worthles and while you harassing opponent waiting while his hp drops low enough to kill lane phase can end with out mf snowball, and here we came to second thing - in mid-late game double up has little of use and third thing it is hard to use right in such fast combat.
So it is strange to me to see that in every guide and everyone offers max it first instead of other two, most cool abilities, for example i first take make it rain to have some control, which helps and catch and run, then i max impure shots which gives a lot of sweet damage in early game there every drop counts and only rarely take double up on 4 lvl maxing it last.

or even
e-w-w-e-w-r-w-e-w-e-r-e-q-q-q-r-q-q
would give some control and more damage in eraly game, which is very helpful then u agressive, gank other lanes or your team comes to your lane.

I agree to a certain extent, though she is strong early game than other AD Carry, she get destroyed by any champion who scales more on level than gold, a typical example would be Leblanc or other early game AP Carry and some top lane champion too. She needs to snowball and win, not holding the advantage to late game w/o doing anything. Remember that AD Carry deals the most damage late game, if they have a hyper carry such as Kog'Maw who is fed, your team will get crushed easily.

Hey, I kinda disagree when u tell not to pick mf on late game teams, you can't really trust in a full late game comp, she might be exactly what you need to hold the early game.

One does not simply name a build "Tons of Damage" without triforce.
