Jawas are fantastic in the raid BUT, Jawas AND Droids aren't fantastic...
I'm hoping someone comes up with squad compositions that will make them both great. I've been told GS can replace CN with droids and still log a good score... if that's true then maybe someone has someone to replace JE with the other 4 jawas to still get a good score.
I've tried everything I can think of to use Jawa, Scav and Dathcha and get a decent score (at least 1m in p3 normal) and I haven't found anything yet.
Most guilds need droids for P2 and can use chirpatine for P3 so it kind of leaves Jawas out in the cold (and they're a bit gear intensive).
So for now... I'd say grab shards and pass on the rest.
