Ah okay Dengar then instead of Rex. I've seen Rex in all those Raid guides, that's why.
Rey: The "farm or not to farm"-guide says:
Rex is the new cool commodity since was added recently in guild shop. He is a TM manipulator thats why you saw him. He shines with other clones which are in decline now. Still a good unit to have. He will be more useful in future since meta is going towards Empire now and he can counter that a bit with his tenacity up buff.
I don't want her atm. Maybe later when the speed mod challenge is viable, but this will be only in two month or so.
She is a weak pilot, her ship is mediocre at best. But she is a powerful dps. I started farming her as OP stated in guide, but I have no idea where to put her... ;/
Good call with GS farm in middle of Lando, in fact I've done the same on my gameplay.
One small detail - going with Ahsoka before QGJ in cantina shop depends highly on your fleet bracket.
In the one I'm in right now I don't need her ship to get top1. This might change in the future as more whales come around.
But as it is now I only farm her from hard nodes and nearly unlocked her now. In a competitive, but oh-so-so bracket you'll be fine off with JC, GS, Biggs, Sun Fac and some of Resistance Pilot, CS, TF. She is still nice to have and you should get her ship. However in a weaker bracket you can easily spend those 400-800 tokens a day on her shards, instead of all on ships. Granted - only when you 2* at least 6 of them first.
