Bedard is saying in interviews that Batman is rearranging the Outsiders so they can do the dirty jobs the JLA can't without losing their super hero cred. Seeing as how Vixen was a member of Task Force X isn't she already as big a liability to the League (by that logic) as any member of the new Outsiders?
I wouldn't hold being a member of the Suicide Squad against Vixen. Heck, Ray Palmer/Atom was a member of the Suicide Squad before the series got cancelled.
At one point I thought maybe Vixen would be a better Outsider than a JLAer but JLA #11 changed my mind completely. Vixen should stay as a member of the JLA for the foreseeable future.
