The fact is that, even if I like a lot his idea and his mod, the first times I noticed some Spartan hoplites that in 1vs1 managed to push inside a phalanx and break its formation. I don't know why this happened and if I was just unlucky but I still wanted to make some changes, searching a "compromise" between different strengths.
Remember that Macedonian phalanxes have the spear attribute as well (with my modifications, that is). When you take guard mode off, they can push with immense force as well. I did this to have phalanxes have a crushing push but less killing power (reduced attack) until the enemy breaks and routs. Battles also last longer this way.

- new, I added the short_pike value to hoplites or hoplitical-based units that hadn't it, in example Sacred Bands or Dacian Phalanxs. However I didn't add it to Helvetii phalanxes and Alpine phalanxes.
Interesting. Did you test the spear and sword equipped infantry (Dacian Light Phalanx, Sacred Band, etc.) after giving them short_pike? From my tests this was extremely buggy. I'll try it again though. I hope you're right.
