You have a roster that can go anywhere, which is good! I think what anyone would say is to work your way towards the end game, which right now are Galactic Legends. My advice would be to pick a GL and stick with it. My advice would be JMK cause he's one of the best and also cause I think you're objectively closer. If you don't wanna do JMK, pick your fav! At the end of the day, it's just a game, so have fun!
I would also set some secondary objectives like focus on Geonosians for WAT. Having Geos ready will help get you into a really nice guild. Looks like you're already working on Shaaktroopers which will help with crancor and Ki-Adi-Mundi. I think you know the direction you need to go. Just remember to have fun!
