I only have one point in Die Another Day (since having more than one point in it isn't worth it), but the four seconds of near-invincibilty saves me a lot. You can use it on low levels to reduce a Loaderbot's damage to 200 for two attacks, likely saving your life. If you're trapped by a massive swarm, you can shoot in front of you for three seconds, clear out the zombies there that are blocking you, and the run away, shooting behind you every now and then. Honestly, I think heavies should start out with Die Another Day instead of Hold the Line.
