You and me both. I think i FINALLY got some good RNG on mods. Had apparently one of each mod (sans arrow) with speed secondaries and a green arrow with +4 speed primary hit the shop. All combined lvl'd to 15 got leia up to 242 speed. I was stunned.
At that with: G10 SThan, (160) all 7 abilities, G9 luke (170)(all 7's), G9 Leia (242) (all 7's, omega main) and G8 R2 (201) (all 7s, omega main) i went 0-15 or so. Went back upped luke two attacks to omega and finally got it.
There must be some WILDLY different RNG's out there for people to get it with what they claim.
As a tip, use R2 to stun the trooper with the crit buff until luke can remove it. That's what got me through in the end.
Now...here's hoping i have everything on hand to 7 thrawn in 3 week. 70K PS mostly omega'd...Fingers crossed :)
