Ideas and suggestions

[mitra]

If your group is perforated you receive the same penalties of rear attack; the single soldier attacked from direction where the weapons cannot defend him can be hit easily. So a dense formation will have alwasy a big advantage over a loose one.

btw Do pikemen get bonus for additional rows while fighting with spears and in formation (like in MTW)

Pike have a mininum range from the enemy for be use but can be used also a certain number of rear ranks. Over this maximum number of ranks, the supplementary ranks have the sense of create group mass against perforation. A wide unit can easily attack on the flanks but can be perforated easily, a deep formation can be attacked on the flanks but not easily perforated.
