Seems to me it kinda lost its edge over other horses.  Its speed isnt high enough to make a difference like the maneuver boost you get from an arab.
So,  as a biased little courser lover,  I would like this horse buffed a bit.  imo the market appreciation of it also displays its shortcomings.
I would like to hear opinions of people who know what they are talking about.  After all,  I aint talking about bow-balancing either : )
my suggestion:  either +1 speed or +15 HP
reasoning:  either of the two makes it better vs (mounted) ranged,  a feature otherwise only achieved by maneuver,  that it does not have,  or maybe armor.
must admit that i just love being fast and miss the old speed of it.
