I don't think Treyarch understands the meaning of the phrase, "Second Chance".
Second chances are just that. A SECOND chance. Not a third chance. Nor a fourth chance. And a fifth chance is now clean out of the question.
So, with this reasoning down, what's the reason to not camp? I mean, use your overpowered Stoner63 and other guns with your prefered perks, include Second chance, a voilla! You've just made it several time harder to die, ever. And if that odd circumstance just come along where you do die, fret not! Just quickly get the Pro version, and some friendly bloke will waltz over and revive you. Rinse and repeat until you win.
