Except there has to be some reasonable expectation to be able to get the other team to submit. I'm not talking about a powerful foe that you hope you can outmatch - his null field hasn't ever been breached. He's never been knocked out. The Karmic Blast may work, but outside of that, he's stopped Quasar, Hulk, etc. Once in the field you're less than human as you can't move at speeds fast enough to do any kind of damage, at all.
I'm just saying it bears consideration.
