The mount system adds a new passive tree with 16 passives related to horse riding and mounted combat. This includes a couple of specific updates such as a reduction in horse speed when shooting a bow on horseback in the interest of balance and some optimization to allow horses to be seen from a greater distance. Additionally, due to the new horse-related passives, every character is getting a free abilities and attribute reset that can be claimed between now and Friday, March 27th.
