A good choice, its really the best option.

Its either vanilla Phalanx which is unhistorical.

Guard mode, which has to many bad side effects.

Short_Pike, which also has to many bad side effect.

Smaller radius, like 0.2 for Hoplites. Which basicly has no side effect I can think off, other then Hoplites fight better then ordinary spearmen, but seeing that they fought in a shieldwall its quite logical.

Anyways, I really hope that EB will also use it as all other mods.
