Do knights have reduced accuracy when swinging greatswords from horseback?

Title says it all.

Thanks gang!

Should not, no.  The only change should be trying to use polearms when not mounted (negative), polearms when mounted on a different beast other than your bonded steed (normal), or polearms on your bonded steed (a small bonus).  Other weapons should be consistent regardless of your state.
