This will be my second attempt and i'm nervous a bit. However, i've made a sizable jump.
First time i was 76 with Ezra at maybe 9? Could have been 8. maybe 2 were 8 and 2 were 7, zero omegas.
Now, 85. Ezra could be 11 by then, Zeb 10, the rest 9 and all specialed omega'd. I think ezra is only short a zeta and everyone has a total of 2 omega's minimum.
Mods could be faster, but I have a a 242 leia and a 210 R2 to pull speed from :)
Quite honestly, they weren't my main target in the interim either. I did focus them to omega the shared specials, but that was it. In the meantime i've built up empire and my CLS team. So, if I can do it hopefully on take 2, you should be able to do it on this round.
