Thank you, as always, MasterSeedy.
I'll definitely take this into consideration and gear up my toons following this list, I think you make a lot of sense.
I currently have 90/145 shards for GK, as I haven't been in this guild simming HAAT for so long, but I should have him unlocked in a couple of weeks. How does he fit in this suggested gearing list? He'll be 5* initially, so not that useful, but I know he's important in this squad. Mace (his substitute) just doesn't cut it.
Unfortunately I only have 47/25 Bastilla Fallen shards now, but I'll definitely move her up in my own farming priority list (I know that's what you had initially proposed, sorry!) and hopefully she'll be good enough to substitute Darth Sidious in the Empire/Sith squad soon. The only other imperials that I have that could potentially be but in there are Royal Guard and Snowtrooper (got a lot of their shards from Bronziums) and Magmatrooper, but Bastilla is probably better than either of them. I also have all the shards I need for Savage, is it worth it gearing him?
Regarding the GW tokens, yeah, I have a lot banked and mostly only using it for the Geo Ships. Geo Soldier's ship should be completed soon (88/100). I'll also start buying Imperial TIE whenever he comes up, but my TIE fighter Pilot isn't that strong, so I doubt that ship will end up getting much use.
Thanks for the advice on the Zetas, I'll Zeta EP and Vader before moving back to my GR Zetas.
