I too love the Luxemburg map, it is quickly becoming my favourite map on the site.
With all of these complex maps coming through the foundry it was nice to see such a basic, simple and clean looking map made. Personally i am not a fan of all of these maps with complex bonuses and strange ways of attacking non adjacent territories. Which is why this map is one of my favs.
Personally i hope they don't change anything surrounding the gameplay as i think that is fine as it is, and personally i don't think the gameplay is unbalanced, i think everything about the map is amazing!!!!
