hmm, some input.
due to the heavy lance having something like 65 speed, 0 wpf lancing is VERY SLOW. I used to do 0 wpf lancing, but right now the extreme time needed to prep and release the lance means a huge inconvenience against other cav and infantry as they have plenty of time to dodge you. The lance speed at 65 seems to me was a decent nerf and that can remain the way it is.
Lancers do have drawbacks, as a 1h on a horse, if you are ever stopped, you can still fight enemies. As a lancer, if you are stopped chances are you are dead.
