Who should be my second 6* r4?

Boli

I have enough resources to r4 Kingpin, Domino, or Rintrah. Kingpin and Domino are both awakened. I'm leaning towards Rintrah but I like Domino as well. Kingpin is already doing so much damage as I have him now.

I would suggest Domino. As she has sig, she's gonna be a beast on BG defense.

Kingpin best one Valkyrie close second but if you like him Juggs is attack monster

Boli

I do like Kingpin and use him a lot. Valkyrie is good but I don't use her as much. I agreed on Juggs, I used him for the GM fight but I use Rintrah quite often and he can be a good defender.

Kingpin, using him + hood is 100% immunity to shrug off debuffs.
