I use this build when i have a team of incompiedent idiots usually. Get over it. If you dont like this build build her your own way. Geez. If you want to build something totally useless try a mana regen tryndamere/rumble/kennen. Or a dps morgana etc. You can use miss fortune for just about anything, same with other champions. Anything somewhat logical works. If people can build a dps soraka why cant they do a more tanky miss fortune.
Oh and loving the downvotes. lets see if i can get rated as the worst build ever :D

Wow, if you wanna tank, play a tank. lol. MF is to stay in the back or gank towers.

Why the **** would u go tanky on a AD carry, AD carry is suppose to stay in back and nuke everything not stay in front. You talk about to survive in single or 1v2, you are not suppose to leave ur team.

no i don't like it
if you play smart and have good positioning u dont need so many tanky items
just doesnt work for me sorry
and wtf is up with the runes lol

I know miss fortune isn't a tank, but she is a carry and valuable to keep alive. Her massive damage output is useless if shes dead. Runes are personal preference, if you would rather different, build however you would like to build her. I'm simply showing an alternative way to build her that focuses more on survival.

a) doesn't work
b) sucks
c) useless
d) ****py skills for triforce
e) not a tank
f) not a tank
g) worst runes in the history of runes

Like the items

It does work with double up, the second shot uses the effect. The idea is to sell boots if trinity force is needed. Im going to involve a situational items section soon. Adding a Phantom dancer instead of the blood thirster could work. hmm ill sleep on it xD

Not a bad build, I never knew sheen worked with double up. I think you should try to fit phantom dancer because of how well it works with IE. Also a last whisper. This can easily be countered by stacking armor. But then again, with your tankiness you can probably get to their squishies without dying TOO fast.

You have 6 Items + Boots, so do you just sell your boots or something?
I use the Sheen+Infinity combo on Shaco often because of the guaranteed crit from Deceive, inresting Idea on MF.

Let me know what you think, constructive criticism is very welcome.
