Just saying, flew RAC/Soontir again and list impressed me some more. Definitely, going to want Palp/Krennic as the combo for RAC.
Krennick - best uses
I think a RAC supported by a ptl, Palp, LWF Reaper could be amazing. The reaper can jam something and evade as it's action. RAC has I dunno Rebel Captive, Kylo and HSCP /Gunner. RAC can blind a ship and take less damage (potentially) from a jammed ship and really just buzz saw through things. It could be great as the Reaper will be pretty tough to take down. No Krennick in this list though I know XD
You put Krennic on the Reaper, then it can help clearing shields even with its no offensive mods, and palp on RAC.
