Some Ironsides math:
Hank flurries on Toni. Average damage on hit is 4 and change on negative flip. Stone for reduction, average 2 and change, gain adrenaline. You end with 6 damage, 3 adrenaline, and you've dealt about 6 back. You activate, gain 4th adrenaline, finish Langston, heal 4. If you're playing the emissary, 5. Regen mage, you're full.
If you get a clean line on any key model with a low minimum, your lure becomes a better attack than swinging. You get up to six chances to make your enemy hit you, dealing 2/3/4 back, and at the end of it all you heal back up--if their minimum is 1, you essentially took nothing.
