I didn't change the math. I pointed out that the 28800 you were fixating on was due to the SMN's defense buff. An LB5 snipe with 20% DR is 43.2k damage, which puts them into death range of even a standard drill (51.2k total damage.)

You tried to be cute with the 28800 but forgot (or weren't aware) that SMN has a 20% DR buff they can give themselves or others. I'm simply correcting you on that. Why are you so mad?
