If it helps going forward here are my notes for those feats.
Sector 4 - Vane/Silvo survive: If you have Reva, use Reva, GI, 7th, Vane, Silvo vs Rey Training. I find Inquisitors are quick to deal with this team, and subbing in Vane/Silvo I was still able to get the win here - focus first on RH Finn if he's on the team, followed by R2 & Holdo if they're on it. I like to use 7th's ability block on JTR or BB8 since it will dispel foresight and still hit them.
Sector 5 - Pirates team: This was tough for me, and my new Pirates are all sitting at relic 3 (except Hondo who is r9), and I don't have Maz. I used Ithano lead with Vane, Silvo, Quiggold, and either Brutus or Hondo. As I played around between the two I found Hondo's basics were doing more damage than Brutus. This team was usually doing pretty poorly at 80, sometimes 90% stamina though, so I'd have to get them in the 90s, do an attack, sometimes would try two, and wait for them to replenish. I believe I used a stim or two to wrap this one up. I should also note that I have Vane with 6 dot gold mods suited for defense, protection, and health (though he still doesn't feel beefy enough). My Brutus has a zeta on Mutineer, and Hondo has both zetas. I used this team mostly against First Order and tried to take out Sith Trooper and anyone with an AoE. There's probably a better team for them to get this done against but i haven't yet figured out which team.
My Savage is r1 and got walloped against that Sector 3 boss. Not sure what relic he would need to be to get the win. I only tried once or twice and decided I'd come back if needed. With the "survival" feats I often use GLeia and put them as the 5th, fight against a team with only 1 AoE and take them out (Phoenix: Sabine, FO: Sith Trooper). Log roll and select the suvivor, then have R2 stealth the survivor. Usually by then the battle is about done. Problem is the need for this team to have constant stamina. So using my Inquisitor method above helps a lot.
