Pfft, Plunkett didn't invent the supine position. Check out these Japanese prints from 1612.

I understand the need for balance but if Holdfast is going to have Cavalry then I don't see a problem with England only having rifles. we have to understand that Everytime I have been in with an event in NW with all the different specialties, I have only seen 2 regiments in NW repulse full heavy and Light Cav, KPR and LIR. These two are one of the most expierced marksmen in that game and they are a force to be reckoned with.
A conclusion I suppose would be why I love the Napoleonic era. as it involves rock paper scissors style and for once Tactics and weaponry were actually at a balance with one another.
