Should I use my sig stones on 7* sasquatch?

I'm still paragon and I only have 40 sig stone on me from act 8 and 9.1 exploration and it will take around a month for me to reach valiant (luck be doomed, I got a tech 2->3 while I just used all my mats for shuri r3 and don't have another r2)

No, he doesn't need more than 20 sigs for now

Sassy’s one of those defenders where the sig increasingly helps his brick-wallness factor as a defender, however sig stones are too precious right now. You’ll keep pulling him and increasing his sig naturally, use those stones elsewhere.
