I think you are much further from a GL than you think. Your Krennic and RG still need some work. Krennic especially is a single hard node farm. Rest assured, once the other requirements are released, we'll see a lot of other toons required at Relic 3 that you are probably far from.
We don't know what SEE's synergies will be yet...if it's just sith you might be ok, but if it's Empire or First Order, you aren't in great shape for a supporting team. Your clones for Anakin, on the other hand, are pretty good. And you are nearly there on the requirements except for some gear on Seps.
If you are two months away on a ship, you'll have enough to 6* right after unlock. Keep a laser focus on the requirements, don't spend GET on anything else. I disagree with the above that he won't help you in arena. If your shard is young enough that can get top ranks with DRevan, GAS will help you in arena unless everyone else is close to SLKR or Rey (which you are not). I do agree with the above, however, that you don't want the GP bloat until you have a more well rounded roster, and GAS will be good for GP.
Don't lose focus by looking at the shinies. They will be there when you get there. Keep going hard for GAS, and after you max that team, switch to focus on a GL if that's what you want.
