Giving Steppe Lancers a niche

Directing to some past suggestions of giving him a niche:
Making the Steppe lancer a raiding unit:

Making the Steppe lancer anti archer cav (not a big fan anymore of that idea, since melee pathfinding has vastly improved since then and made knights pretty balanced against archers):

Making the Steppe lancer a rewarding micro intensive unit:

But since most of them are massive reworks I kind of like this your idea of making them the fastest unit ingame.
