Galactic War.. Should I farm Phasma shipments?

Many thanks for all of your replies on this thread guys. I always get a lot of help when asking questions on these forums. I went ahead and unlocked Phasma but since doing so she's been a great additional to my DS battle squad as she's teamed up with Poggle, both toons buff up my entire squads damage hits and crt chance so I'll continue to gear up Phasma (now on gear VI) and in the mean time farm Lumi shards through GW and hard battles
