Based on your response there, it still looks like you're focused a little too much on toons. When you say you "still need URoRRuR'R'R, Krennic, Lobot, Rose, Visas, and Bossk," what do you mean by that? Exactly what do you need them for? What's their purpose (other than to fulfill the OCD/Completionist drive? I see a utility for Bossk in the Bounty Hunters that you mentioned, and maybe Visas in an eventual STR team, but you really probably don't need any of the others, at all. Certainly you don't need them more than you need better gear for all of the toons that you already do have.
Same goes for Dooku. He's a pretty weak toon at end-game at your level. He doesn't really serve a purpose in any team. Sure, they might rework the Separatists and make him awesome one day. Work on him when that day comes. Don't farm him now because he might, maybe, one day be worthwhile. Instead, use those resources for the very, very many characters that you already have that are good right now!
