Sorry to dig this back up but to help people clarify between the rumors and the facts of MF...

In that if you scroll through it it should answer all of your MF questions along with half a dozen other commonly asked questions....

More MF has diminishing returns but still returns...more runs does not mean worse items (outside of Quest runs of course). Is it luck dependent? Yes. But essentially what this is is you have a percentage to "win" and MF just increases that percentage...but as long as a monster is actually able to drop something in theory you have a chance then even if you dont have any magic find on the character at all.

And for the people who are new to all of this rune drops are not affected by MF from anything that i've read.
