All are 7* (except RT 6*) lvl 85 with omegas and Finn is G8, Rey G10, Poe G8, RP G8 and RT G8. And they all have the recommended mods based on the Mod Advisor on Crouching Rancor.
You have to make sure you get the right RNG though and land expose or else you get annihilated. The fact that round 1 starts off with a 8 turn volley fire from the B1s is aggravating so you want them to hit Finn and Poe first and then methodically use your expose abilities and most important use the special event ability with Rey
