And Greedo can't be used for Falcon so I would suggest IG-88 for BH team for double use.
I had checked their roster already: they've got a 7* IG-88. You could conceivably skip Greedo entirely, but Greedo is easy to get & IG-88 is too squishy for the Chewbacca event, so that's why I suggested him where I did. (I mean, Greedo is squishy too, but not as bad as IG-88 who just disintegrates in that event.)
If your doing LS Hoth you might do Cassian before Asajj, otherwise if you are able to farm NS then keep Assaj ahead.
Yeah, without more details, I'm making some assumptions, one of which was exactly that one: that they're in a guild doing LS Hoth TB for at least another few months.
If I'm wrong, though, Zumwan? Schwartzring is correct. Cassian is only a higher priority if you're currently working LS Hoth TB.
Either way, though, Assaj should be taken to 7* soon.
Fixed your math
Oh, d'oh!
Thanks, Schwartzring.
