I meant “restrict to both designs having Weapons + Armor >= 10” (which I admit may be a moot point since Weapons + Armor > 10 is out of the Pareto frontier anyway).
Weapons 6 + Armor 8 is obviously strictly worse than Weapons 6 + Armor 4 (cost less and do the same), but it’s even worse than Weapons 9 + Armor 4 (same cost and do more). And Weapons 9 + Armor 4 is strictly worse than Weapons 10 alone.

There is nothing strictly better than armor 10 weapons 0, which contradicts the rephrased way you put it.
