Carl: Did you consider to remove spear wall formation from all halberds and raise their stats accordingly? This will make a sort of cheap weak AP assault infantry from them, similar to billmen.
It's a possibility, but as noted a couple of posts ago by me, a number of factions use Halberds as a replacement for pikes. They really need the Cav defense, and without spear wall they are going to struggle to provide it IMHO. This is a particular issue for the Danes.

Also, HRE, France, and Denmark already get 2-handers, I also believe the same is true of the eastern factions that get them, (Although I haven't played those yet so I'm not sure TBH).

The problem is that turning them into AP Pikes risks making them IMBA, yes they cost about double he price of a comparable Pike unit, and are slower. However, they are much more missile resistant in general than most Pikes and the high level Halberds are cheaper on upkeep than the High level Pikes, (although this isn't an issue for custom Battles it is something that has to be remembered as the campaign is the most common form of SP play, for reference low level Halberds are similar or more expensive than the low level pikes on upkeep).

In other words we have an issue in which we can't really make them 2-Handers, but if we turn them into AP pikemen we risk unbalancing them. It's a double edged sword.

Thanks for putting this together. I was only able to play an hour last night after installing the BugFixer. I started a new campaign as Scotland, so I haven't had time to see any effects but after reading through the readme, it looks like I will be very happy for a while.
Thanks for the opinion.
