This guy thinks he’s smart, but he only looks at units one dimensionally.
He thinks that pure mathemetic cost, and power is what makes somethingn useful or not.
What he does not understand is the importance of threat power and utility, exponential defence, strategic placement, and turn order.
For example: Going by his calculations, a Dark Skies strategy would be an absolute and complete folly against even the most simple minded opponents. Where as in practice, mid tier to high tier players use components of the strategy with excellent success against evenly balanced and competent opponents.
