Right now bears (includes taur dogs) just straight beat horses in mounted engagements. The bears have smaller hit boxes, are faster, have higher baseline defenses, high much higher HP, turn tighter and faster, and have similar stamina to that of horses. In a 1v1 trade with a horse vs bear you will always lose with the horse. Additionally if you have necro, you can have a horse and a bear to ride if one of them dies during the fight. I recommend cutting the bears total stamina pool in half to meet the design philosophy of "horses will still be the premier mounted pet". I can see counter arguments of pet point cost being considered, but I still think the bears will come out on top even with half their current stamina considered. Regarding necro, there is no counter argument.
