Crossbones: what Sig do you need to have functional tenacity?

My best guess is a Sig of 140.

Am I even close?

At sig 80 he has a 65% chance to shrug off debuffs so he's on par with KP. Though with KP you know that when he reaches 8 debuffs he will shrug everything off regardless. Now, if you're using Crossbones on a node where the you get the debuffs when you hit the opponent then his DAAR should be more than enough to compensate.
