Mounted Spirited Charge

[Baseili]

I'd like to suggest opening the mounted spirited charge to use all melee weapons, size small and above.
Presently, requiring a mounted only weapon renders the class into an almost lazer focused niché in both use and character type, limiting it purely to a medieval knight jabbing away at enemies point-blank with a candy striped or christmas tree light covered 12ft stick. While theres no doubt the ability and its unmounted version are effective, I believe the demand of the lance is more a stick in the mud than a banner of the class.

To open up the class's mainstay ability would allow people a great wealth of character concepts; desert nomads with falchions, raiders with axes, cavalry with scimitars, samurai with katanas, knights with greatswords or simple guard with halberd in hand.
Furthermore the ability only takes the keen properity of a weapon into account, its remaining calculations do not, damage being character level x 6 + 1d20, improved critical feat effecting crit chance (20x2) and attacks being limited to 1. To my unknowing eyes this would appear to be a small quality of life change that allows more variety in both character and class use.
