The charge attack and giving the stand ground command a use for melee units.

The Coustillier, and history, has got me thinking of a good use for the stand ground command. What if when put into stand-ground mode, foot-soldier melee units got a bonus versus cavalry based on their use?

Like the champion line and other misc melee would get a small bonus when using it, but Spears and other anti-cav units would get a large bonus vs cav when using it? And I'm talking "LARGE BONUS" like +80 anti-cav damage to off-set the fact that your melee units are in stand-ground and to make it worth using against high HP cavalry units/Coustillier. This bonus would also have a charge bar so it can't be spammed ruthlessly between stand ground and defensive mode.
