As far as my understanding, it was. Long bowmen were far more valuable because the costs associated with losing a knight was high. Infantry were given various polearms, and cavalry (or knights on horses) were given lances and spears. The kinetic energy from horseback functioned as good or better than trying to wind up swings of a weapon. Also human mobility is less than that of a horse before even accounting for armor, so being demounted from your horse mean almost certain death.
Swords were a last resort. A “running away is better” type of option. Being good with your sword is like being good with martial arts today - better to have it even if you may not use it.
