I'm too lazy to DL mods.
NO, NO, NO. Joints = weak spots, joints in a phalanx are BAD. BAD BAD BAD.
Jesus, haven't you guys ever watched any time commanders episodes?
joints either way are bad, even if you are using it like a bowl for your enemy. At least make it square, phalanx can't effectively attack as a single unit if they're hitting at an angle and they're not really mobile enough to effectively circle with speed to hit the flanks of an oponent.
So instead of organizing like this
\_/
organize like this
| _ |
and get the enemy to engage the phalanx in the middle, then get the two sides to come straight in
Also, I hope you're not using your phalanxes as strictly defensive units, letting the enemy to come to them, back off a bit and charge as they reach where you want the confrontation to take place
EDIT: I'm pretty sure that Hannibal used the tactic of the |_| on a much larger scale in one of his battles, Cannae maybe. I don't know, I have a book about it somewhere, maybe I should check.
EDIT2: at least TB666 seemed to keep his units close together (although it looks like the only reason you won that battle was because the stupid romans sent their cavalry in first, right onto your spears), Theredintheskyisyours has his units spread all over hell, and it's alot harder for a phalanx to charge from a \/ formation than a \_/ formation. They have to turn before charging.
EDIT's 3 and 4: spelling
