Something that has always confused me is EB's choice to give Camillan Triarii the RTW Phalanx formation. Specifically, if the Triarii faught in a way comparable to classical Hoplites, and if it has frequently been said that Hoplites traditionally used what is closer to a shieldwall than RTW's Phalanx formation (ie a Macedonian-style phalanx), then shouldn't the Triarii fight without the Phalanx formation?

It strikes me as being a little inconsistent - is there a reason for choosing the Phalanx formation over a formation more like that of a traditional Hoplite, or the Hypaspistai secondary attack?

Or have I missed something entirely?
