I think i see what CA were thinking.

Now in the most basic layman way of explaining what i see. i will say

Back kills kill to many people. and to compensate you haft to moove your men futher back.

Moving your men futher back leaves your muskets unprotected.
So they increase musket powere and fire speed to make muskets not get totaly out classed.

but then they had to slow down unit speeds so as the infantry would not arive to protect the muskets as quickly as they used to.

to me this means.
You simply cannot just reduce musket fire power and speed.
Without re-instating foot unit speed.


Becous weak powerd muskets + slow reload + slow mooving infantry forced to be far way = Muskets die fast to cav.

i believe that ca saw this problem as a Big picture and not just Muskets vs a single unit.

So i guess the best way to fix it all.
would be to reduce fire power and increase reload rate Both of which would be done in tandem with increasing infantry speed.

This should allow people to avoid the back kills.
Allow others to charge Muskets.
AND allow the defenders to get there infantry in to the battle before all of there muskets rout due to a cav rush tactic.
