Legildur said:And therein lies my reason for accepting the RAW without further consideration. And I would think that it would also guide others to making their own ruling.
If you accept that lances are the pinnacle of mounted combat, then accept that they gain all the benefits of a two-handed weapon (as per the RAW) while wielded in one hand if mounted during a charge.
If you do not accept, then house rule away using Rule 0.
Otherwise, why is there so much argument on a rules forum when the RAW are relatively clear (as Hypersmurf pointed out)?
Because they aren't "relatively clear" on this particular question. An awful lot is being read into a single sentence footnote in the weapon description.
The lance is the best weapon for a mounted charge. It is a reach weapon that does double damage on a charge, triple damage if you have Spirited charge. There is no other weapon in the PHB that does that.
Whether or not it gets x1.5 Str damage when used one handed doesn't change that.
