FAN worth before Admob?

Guys,
Since we all are seeing the huge drop in Admob rpm these days and some experiments need to be done to make sure that nothing is left out.

So i want to include the FAN network again in my waterfall. Since i will use the manual way to add the network without any mediation and integration eats lot of time and i may not do it if its not worth.

So i want to know if there are any revenue differences if we use FAN before Admob. I want to know this based on the latest stats.

Ofcourse we need to add another network to fill the ads if FAN is being used.

Hi
To show ads user has to install facebook app and login to it otherwise, in your app no FAN ads will show this is a big minus for me…

Why not integrate both with Enhance?
