torch if yu havnt done abyss . corvus for general play . capiw for act 6
If thats your roster I'm sure you don't need our advice.
I have 6* Cap at R3 and he is awesome, even at Sig 40 and will help you clear 6.2.6 Champion, however Corvus would be awesome too
Capiw probably i love corvus but the ramp up takes too long
All of them. How did you get all of them?
