Not really agreeing with it so far.
for one its important to get to 7*, don't stop at 5. yes those are longer unlocks, but if you are in a guild that runs 7* rancor or HAAT you won't get any rewards unless you have a 7* team. Plus 7* phoenix (assuming you are in a newer shard) should keep you in the 100-150 range and will take out GW consistently and is necessary for 7* palp, which is a very easy fight for them (I set it to auto attack and still beat it). Sabine should honeslty be a side project- you don't need her unlocked until level 60.
ST is situational, if thrawn happens to land right when you have a level 70 7* phoenix team then ST is almost moot, as thrawn will replace him anyway. Important for an imperial trooper team still? yes, but that is very far down the road. Snowtrooper is not needed at all at this point.
honestly I prefer a "source" type strategy since character will advance at different rates based on where you can farm them.
cantina- hera/ezra -> TFP -> (KRU/KR)/farmboy luke (depending on timing of last bb8/cls event) ->finn/vethan/vetchewie
cantina store- chopper ->FOO ->poe
arena store- kanan -> tarkin -> princess leia/sthan
GW store- zeb ->biggs ->CP with tie fighter/biggs ships as available
guild store- old ben/gear -> fosfp/gear
ls/ds battles- all gear until level 50, then unlock sabine, then focus on rey and RT.
starting off there's really no need to farm 6+ toons for specific teams. focus on 5 toon teams.
this way you get phoenix.
phoenix is needed for thrawn and can easily beat 7* palp.
that's 2 of your empire team, vader will come with accomplishments and from fleet store shards. TFP and tarkin finishes up empire team.
empire team gets you r2, FO team gets you bb8. that's 2 of your resistance team. scavenger rey, finn, and poe finish it up.
your CLS team is ready
your JTR team is ready.
you have a scoundrel team ready for the max tier. you will lag a bit in this area, but you can't buy shards with credits and that's what's more important at this point.
