My suggestion is that there are longer spears/pikes that are over 240 in weapon reach. I find that the AI actually works very well with pikes/spears when they are in a formation like with this mod. I have used Black Iron Spear (32 thrust dmg, 85 speed rating, 230 weapon reach) for my CKO sergeants to great effect in open field battles, it works amazing against enemy cavalry, and it is pretty decent vs infantry if in a formation and not too spread. In sieges it is pretty bad but that is just how it is. So back to my request, I wish there were longer spears or pikes (up to 400 weapon reach), I have tried this long range pike in another mod and the combat felt very realistic and amazingly fresh to have it used by your troops, so I am sure it would work well here. 1v1 spears/pikes are horrible, but in formation they shine. Whether the polearm with 400 range allows a shield or not is up to you, Macedonian pikemen used to wear a lighter/smaller shield and a pike that measured 4-6m. I would advise to not increase damage though, perhaps even lower it a bit, cause the thing is enemies will die very quickly because you got a lot of units hitting the same enemy at the same time due to the huge range, so the enemies die quickly.
Please give me the option to have a pike wall, also would be such an interesting battle if an enemy faction had pikes as their main choice of weapon for one of their more common units, so that you get to fight vs a larger amount of pikes too, but that's just me.
I am not sure what unit would use it in the game right now, but I know that it would make a fun addition and give the opportunity to fight in another way for people.
PS: Please if this gets added, make it obtainable by CKO units.
