Well first, our hypaspistai are exactly that, they use the same formation as our classical hoplites. They might be like in .80, but they are in the internal version and .8 was the first pat of the transition to using our new classical hoplite formation. Second, the issue with equipment for a lot of these successor units is that troops could fight in more than one role, and often did. Unfortunately RTW doesn’t allow you to re-arm your best warriors for the needs of the situation.
