Thanks for the answers. They really help me planning my army building.
2. Using the Scots Guards is a great idea. They should be even more effective at a lower points cost. I will try out bott versions. Should they be limited to 3 bases (in the French list) or to "the smallest unit of Archers" (like the Guards Knights)?
3. Great, this opens up a lot more options. I will probably use 3x 6 or 8 bases at 1/4 instead of 9 bases at 1/3.
4. Okay, that's what I was suspecting, but wanted to make sure.
Another thing, which I want to get 'officially approved': The Burgundian crossbowmen did sometimes use Pavises and I have built some. I want to use them at +4 p/base like in some other lists. Would that be 'legal'?
As this thread turns out to be about improving the Burgundy army List, if you ever plan a 2nd edition or want to publish an Errata, please, feel free to use my ideas for it (if you want to give me credit, I won't stop you, of course^^)
