Light Liberation

Hey all,

So what is everyone using to clear Tier 3?  I've tried STL lead and Barriss Lead.  They just seem to have nothing in common, even the healing is limited to themselves only.  I managed to get to the Kasshyyk battle and the Commando Clones just feed each other TM and I get one shot at that point.  

All my toons are R1, might level to R2.  They are all 4 star.  I am using PVP mods 6 * each mod has 23-28 speed.

Luke with GL Leia mods heavy adding to base 47k health, 20k prot,  173 speed, 102 Ten and 77 Pot. 

Barriss is in heavy SLKR mods with 30k health / 15k Prot / 177 speed added to base.  50% Ten 150 Pot 42% crit

Choda is wearing Jyn mods - 10k health -20k prot - 140 speed added to base / 60% ten 30% prot

I'm wondering if there are specific omegas to invest in or if switching mods around might help.
