#1 SLKR- easy to unlock with lightspeed tokens/bundles. If farming the old fashioned way all toons are available to farm on various nodes except the special forces pilot whick is In one of the stores. Only hang up here is Hux’s capital ship. Farming the required ships takes forever but if a player has enough shard shop currency there are shards available in the shop. Also SLKR requirements do not exceed R7.
#2 Leia Organa- Leia IMO is the best GL in the game. She beats every other GL except Pirate king Hondo is a rough fight but with good mods a Datacon it is possible. Most requirements for Leia are older toons whick many players have had for years. Drogan and Scout Trooper were the shard farms I remember having to do.
#3- JMK- I thought about putting Jabba as my third choice but his squad gets wrecked by to many non GL teams such as Dr Aphra and Queen Amidala. And If Wampa has a focus Datacon Wampa can solo Jabba squads. So I’m picking JMK to round out my list. He has some tough requirements such as Wat Tambor and of course a ship which will take awhile to farm unless there’s a bundle available. But JMK with CAT is still a very good squad that needs a GL to beat it or some kind of Datacon with special abilities that can wreck Jedi or galactic republic specifically. But thanks to $$CG$$ reducing the time Datacons are active it’s not that big of a deal.
