C3PO unlock and 7*

Extremely relieved to have my 7* C3PO after 30 or so attempts. Was dreading putting more gear into them. I did it with:
-G11 Elder 218 speed, Speed/Health mods
-G10 Wicket 228 speed, CC/CD mods
-G10 Paploo 182 speed (not counting 25% obv), Def/2x Health mods
-G9 Logray 193 speed, Speed/Potency mods
-G8 zChirpa 203 speed, CC/CD mods

The strategy isn't any different from what most people have already posted. Don't tunnel vision the taunt guy because Chewie/Han will just mow you over. I went for Chewie immediately after he was unstealthed and gradually chipped away at the taunter until Han was unprotected and gunned him down after dispelling his buffs.

Once taunt guy was down I went for Leia. R2 is the beefiest of all of them. Save that little dude for the end. Wasting attacks on him earlier is a recipe for disaster.

The successful run was very favorable RNG obviously. I think I only had to use an Elder revive once, maybe twice. They just kept attacking different ewoks so I could heal through it and I got really lucky with an big attack missing on Paploo (Leia's I think)

So yeah, with enough runs and enough luck you won't need multiple zetas or g12s. Save those mats boys and girls.
