I will be VERY shocked if they axe Ramona - surely after losing Bethenny, Dorinda - and even Tinsley the mint, production should be able to see the problem is the show losing it's cast members, not losing MORE of them.
I'm also putting it down to the edit, and far too small cast. Also considering the context of the time we are seeing footage from at the moment (US election following all of last Summer), OF COURSE conversations of race and politics are going to be dominating Eboni's thoughts more than ever.
I'd happily lose Leah, and hope they lighten the edit on Eboni as I think she deserves another season.
But a 5 person cast where there's clearly not ALL THE MUCH GOING ON in the lives of at least 4 of them isn't exactly a magic formula to get people tuning in - and the fake events this season (WTF was that Hampton's Beauty Pageant about, it was like a Drag Race mini-challenge) just highlights this further.
Even a quick-fix cast of Sonja/Eboni/Luann/Ramona/Bershan/Dorinda with a couple of Friends Of (Jill & Tinsley pls) would be a dramatic improvement.
