You have the freedom to take any champion to any role...that does not mean you should. By all means do what you want, but if you aren't very good at the game you shouldn't stray too far from the meta...you are basically just throwing away your and your teams LP.
Also don't argue that MF is a support...She has no reliable CC, no heal or any other utility, and she isnt even a good kill lane because she has low damage without being farmed up.
Except her E is great. Build 
-path to take advantage of it's AP scaling and max it first. Even does surprisingly high damage early game. Then just get traditional ADC items (+
ofcourse) and play her as a second ADC.
Of course, it is pretty much only something I'd do as a counterpick to a melee Support/shortange ADC-combo as anything else will poke and bully the heck outta you most likely.
But it does work. MF Support does work... in certain match-ups.
I am going to be maining camille support for a while after she is released so no matter if it is a aatrox or a zyra anyone can be taken as support
You realize that MF Support was actually played in the world finals intentionally, right? Watch SKT v SSG. SSG CoreJJ played it in multiple matches, not just in the grand final but in the quarters and semis as well.
don't worry luv, if i ever play with you i won't pick MF support.
It's gonna be 
all the way, baby.
