Just unlocked cantina node for old Ben, GS is at 4 stars already, should I continue farming GS up to 7 or start old Ben ?

I am non-conventional. I do NOT have Dooku, Daka, Sid, Phasma, GS, or any of those other meta.

I do have Obi (Old Ben).

I am ranked 38 in Arena as Obi (L), QGJ, NS Initiate, Yoda and 5555's (who is only 5*) all else 7*.

Obi is like 3rd highest for Arena players, Lumi is like second and Dooku is first.. but I have done pretty well without the usual squads.
