Use My Mutant Sig Stones for Colossus?

Darksun987

I am a new player, my strongest champ is a 4/55 5* BWCV. I just awakened my r3 Colossus 5*. Is it worth giving him my mutant sig stones? Or should I wait for AA or Namor?

Yes definitely, the more Sig Levels he has the higher the Chance at gaining Armor Up Buffs when Tanking an Immunity and the higher the chance at turning an Expiring Armor Up Buff into a Permanent One.
That Sig Ability changes his Playstyle from Heavy and Sp1 Spam to Heavy and Sp2 Spam.
