Honestly, if you have both Rey and SLKR, this has been the easiest conquest set up in a long time. I'm using fewer refreshes and wasting less time on it. I'm down to 18 total battles left to complete the FO and resistance global feats for the last 30 keycards that I need. Only swapped disks twice. I left four spots open to equip whichever global feat disk I acquired first. Then switched to the other one, and second swap was to swap to dyad disk. Have run with three of the lowest tier amplify agony and a lowest tier unstable decelerator. Had to use a few tether techs and used whatever free boosters I obtained. If you have JMK, that has been able to beat everything.
Really this set of three has been about time management. Getting globals done for KRU/Han wins, Kylo kills, and Reylo wins done quickly frees up FO and Resistance teams. Easier to finish up the FO/Resistance globals at the end. Sector 1 vs. NS team is a cakewalk. Have picked up several stamina stim packs to regen my GL's since they can easily carry the teams. Run two different SLKR lead teams and split resistance into Rey, R2, Finn, Scav Rey, and Trooper and JTR, BB, bros, and Holdo. Can probably run each team three or four times from 100% stamina. Run SLKR down to 50%, give him a stim, and run him again swapping out other FO members.
