I did my fair share of QQing when the patch was released for cRPG about the stabbing radius, but it's not hard to deal with it.
However 1.6k to repair a destrier, 1.3 for a courser? This makes these high-end affordable horses unusable in the game even with next to no armor or weapons and a constant x5 mod.
I feel that these horses, coupled with light armor and a lance (non-heavy) should be able to be able to at least make a small modicum of money, the upkeep and frequency of breaking is just far too high right now in my opinion.
