So, I can't believe how unbelievably stupid they made horses.
Anytime I'm dismounted in combat, the horse just has to join in.
It was one thing for the horse to start beating on wolves with it's hooves. I understand that.
But then I'm parked at the top of a hill, where the giants can't get me, firing arrows, and suddenly for no reason the horse decides it needs to LEAVE THE SAFETY OF THE HILL and go attack A GIANT.
Of course the horse died in one hit while I scream out in anguish.
Then later on I see a dragon, so I dismount and run a bit so my horse will be safe.
Here I am fighting this huge bloody dragon AND MY HORSE CHARGES INTO THE FRAY OF BATTLE TO HELP ME.
And of course the dragons constantly circle, so the horse RUNS AHEAD to SOLO THE DRAGON. I'm RUNNING AND SCREAMING and watching this dragon ENGULF my poor horse in great belches of flame and hoping I can distract it before the horse is a steak.
I paid 1,000 gold for you, horse, stop trying to be the hero of the story. You are not dragonborn.
(thank god for resurrect cheats)
