Well, since cav got nurfed alot and the lance cost went up and everything. Why not have the riding skill reduce breakage of horses? That way, if you are willing to invest skill into your horse, it will break a little less often. I'm not talking about much here, maybe -1% chance to break per level or if chadz is feeling good, -2%.
I guess the same could go for shield skill.
My point is that WPF in a weapon reduces the chances of it breaking. Since there is no riding wpf or shield wpf, cant we use these two skills?
