I think veers, starck, magma, snow and strom troopers could work as a trooper squad (TM gain, TM reduction, AB, def up and high damage)
Then it leaves u trawn, Tarking, shore, death, krenik (prot/HP heal, huge tank, CD increase, TM manipulation from tarking/krenik, aoe dispell, deathmark, daze...)
And also vader, EP, TFP, RG and... Dhaka (i dont have more developed empire guys xD) it means lot of stuns, EP with a lot of aoe TM reduction thanks to vader leader, def up and taunt from RG and dhaka reviving ppl if someone dies xD
Im waiting for new empire/sith content this mont to decide, but those are my planed teams to develop by the moment (shore/death first priority cuz their ship), im holding gear by the moment to see whats ahead...
