Best JTR team with Scavenger or best in general?

I use RJT/BB-8/R2/Thrawn/Old Ben. GK usually just gets fractured and sits there doing nothing. Old Ben's Mind Tricks and taunt through fracture seem more valuable. I might sub in Enfys at some point, but she's too easy to kill at 3 or 4*. She also might ultimately work better in a Rex led Titans style team.
