Mixed units and different ship weapons

[Arcana]

I doubt the ground battles will have any resemblance of this beyond a special ability (or two separate infantry units which you can then muck about with the formations like all other TW games) but the ships might have some sort of formation change depending on where the target ship is in relation to it.

As for whether two different ships of same type (e.g., second rate) would have different armament...unlikely. They'd surely be classed as 2 different ship types if that happens at all.
