Ok time for a release!
The FIRST is the version with the lethality, short_pike, chariots and auto-calc fixes : please take a look to it and give me your suggestions and comments especially about the extra sec HPs.
The SECOND is a version where I added the light_spear fix : the "spear" attribute gives to the units too much pushing power, and so they easily break the formation, if the soldiers aren't kept together by "phalanx" formation. So the phalangitai are left untouched, the hoplitai still have the "spear" to portrait the "shield-push" (but I think the effect is excessive), the other spearmen gain the "light_spear" (instead of the "spear") attribute, that reduce their spread during the fight.
The drawback of "light_spear" is the hard-coded -4 to defense vs. infantry (infos from yhe EDU guide), to counter this I have added to the changed units a +4 to their defense: this make them a little stronger in melee vs. cavalry, but hey, cavalry is meant to die against spearmen in any case! and however from the stats the PI cavalry seemed a little overpowered to me anyway...
I took a suggestion from this thread
http://www.twcenter.net/forums/showthread.php?t=189052 and I tweaked the Soldier Radius of Hoplites: that make them keep the formation without using the "short_pike" attribute, that have some undesired issues; the new values depend as always on morale. I also gave them the "light_spear" because the pushing power of the "spear" is IMO too much for any unit except phalangitai. The version with new hoplites that have changed soldier radius, "light_spear" instead of "spear", and no short_pike is the THIRD
Well, what to say, try these and write your impressions!
