Don't blame math wing for being what it is. A descriptor.
You can fly 3 defenders. But you'll find out that 9 attack dice, 9 hull and 9 shield are going to die quickly without doing much damage. And you can't blame math for that.
Also cards not seeing play came out long before math wing. Sure, with math you can find out that 4 unmodified dice don't roll hits as often as 3 dice with a focus. (The math wing description of expose) but expose wasn't being used long before that.
Don't blame the person describing the box as red for the box being red.
