Help with PVP Team

@Empiric :-) as i thought you are lvl 60, ok. Well, farm the chars you like and always keep in mind where you want to go. Galactic War will get harder for you the better your PVP squad gets - so get a deeper roster with very good healers (lvl 69 Cantina you can farm Barriss Offee). If i were you i would build your Phasma team with Kylo (Kylo replacing Luke or Poggle) and your best 3 Chars. Do not concentrate much on Luke anymore. Poggle´s offense up buff is great, but he really shines in a full droid team or as leader + Geonosian Soldier and droids. I dont know if you will have 5 Jedis at 5* for Yoda event, but most people are concentrating on getting Yoda right now, pushing QGJ in Cantina and for example Eeth Koth in Arena. Current meta is definetely QGJ lead + 1 or 2 Jedis (or +1 Jedi and Tank) and DDs like Geo,Tie Pilot, Rey. QGJ is ok at 4*, viable at 5* in Arena as leader. Droids/Poggle Teams always climb up fast in the ladder, being able to beat any team, and you see some Phasma and Sidious Teams in between.
Just to give you an example: my PVP Team is QGJ (L), Yoda (6*, hopefully 7* this week), Daka, Royal Guard (6*), Geonosian Soldier. Enough damage to end up in top 6 every day, enough defense to stay top 20 over night. I would strongly recommend to farm QGJ instead of Boba (Boba 4* is enough for tank challenge). By the way: calculate a bit. Maybe u should invest 50 crystals in Arena for having 10 fights a day. Try to get top 200 soon. It will help you a lot. Therefore i would stick to your Phasma (L) team first.
