Advancing poses are usefull both for an advancing unit, as well as for a firing/loading one, as for some secs, soldiers holded their muskets ahead. So I wouldn't like to see them downgraded. Also, a firing unit is nice inly if it is in line, while both marching AND advancing men can be decently arrnaged in a column. Third, anyone having bought sets from other manufacturers, has loads of firing poses, half of them kneeling, while advancing ones are few, and marching ones are simply collactables.
