personally think the irregulars issue is sorted
I don't share that confidence. I wrote an Inca list and a unit of 9 Auqua costs over a hundred points more than a standard P and S unit! This is for an unprotected unit that has no impact or melee ability, shoots with a sling, is more vulnerable to shooting thanks to irregular status, is forced to operate in 3 ranks but gets no benefit from doing so and is a minimum of 8 factors worse against mounted at impact. 3 extra bases and slightly faster movement in no way makes up for this.
Unprotected needs to be a .8 modifier. This is not just for the low tech types, it is also important for the later pistol cavalry who often have to be unprotected, want to be in melee but are only saving about 10 points currently. In return they will often give opposing troops a melee POA and, less importantly, become more vulnerable to bows. Could be great for my Imperial Kurassiers from this era but a bit hard on the other armies.
Loose can not be the same cost as C/L, etc. This is clearly a case of getting something for nothing. The ability gap of these troop types is larger than in MeG so the points difference would also need to be larger. We all know what happens to army variety in games that have point systems that hand out huge advantages for free.
