If all five of your units die in a GW battle, does the opponents'...

Characters go back to full health? Also, would a heavy-healer based team be the most viable way of completing it for someone FTP like me?

Yes, since the change I have found using a 2-3 healer team makes it easier to finish, especially since you cannot rotate them in mid-battle.

I recommend Barris and Lumi. I see that other people recommend Daka for her stun and reviving abilities in addition to her heal. Mine is not geared up enough and hardly hits for any damage.

No. If you go in, do damage to the opposing team, all of your dudes die, you can go back with another team, and the damage you did is still there. Today I got to the final battle and threw some ewok, clone Seargent, etc at em, then brought back in my beat up "A-Team"

Still didn't get the job done, but I'm also only level 46...with 53+ on final battle of Sid, Luke, Lumi, JC and Chewie...

Healers are vital
