I am trying some rules amendments

Here they are ...
ADDENDUM /BAROQUE
MODS TO RULES.
ARTILLERY
All long ranges doubled but other ranges the same.
MOVING
Light artillery (c) move as per existing rules
Medium artillery .. can pivot up to 90 % but not fire
To move must limber which takes one turn then move at 1s
Heavy artillery … can pivot up to 45% but not fire
To move must limber and pass a discipline test which takes a move then move at 1s but
Must pass a discipline test each time.

This should counteract the range increase and make the artillery more realistically slow.
MASSED UNITS
If massed units are disordered the its -2 dice not 1.
LONGBOW
Fire as muskets with – for shooting as cuirasses as pistols
Units 5 strong with no firing reductions
STAKES
Stakes for longbow take 2 turns to emplace one to remove and cancel enemy impetus

Looks good.  Doubling the artillery ranges is a must.  Muskets probably can fire too far - max range should be 3 instead of 4.  These aren't rifles!

Still concerned about a few other game problems - mainly VBU 7 & 8 units that are nearly impervious to gun fire, esp with cheap upgrades that allow rerolling sixes in CTs.
