Followers tend to do that. Such agonies they endure over those wily slaughterfish.
Yeah, normally, but the point with the UFO mod is that when you are on horseback, and your followers are on horseback, they are not supposed to dismount unless you dismount and they can't engage in combat from horseback either. So if you decide to sprint away from that wily mudcrab or slow moving troll that is bellowing at you from a distance, they just sprint away right along with you even if the threat has already registered as hostile on your radar. If they are on foot, they will do what they normally do; if they are on horseback they may react verbally to a threat but they do not attack it unless you stop and dismount.
Ulfric ain't havin' none of that, lemme tell you. If something registers as a threat, he stops his horse and gets off and deals with it, even if he has to chase it to Oblivion and back. It is nice in that he still really does have my back even when we're riding, but not so great when I'm in a hurry and we could just sprint away from something that is still far away enough and slow enough to not require killing at just that moment.
Edit: of course we're talking about a guy who once went way out of his way and waded across a river just to kill a mudcrab on the other side that I couldn't even SEE and which appeared to be doing nothing except minding its own business. So I guess I shouldn't be surprised. Perhaps *he* is programmed to attack any potentially hostile creature on sight, whether it attacks him and his allies or not.
Best part about Ulfric is having thu'um backup. It would be most awesome if they could make a mod where the dovahkiin could "teach" him a couple more low-level shouts.
Oh I'm sure it could be modded in, none of his shouts are voiced anyway. It would just be another thunderclap for a sound effect. You can use the console to add and remove the knowledge of spells from NPCs, and I'm pretty sure you can do the same for yourself with shouts, I don't see why you couldn't give Ulfric additional shouts and just use the same sound effect. Altho realistically it took him almost 10 years to learn the two he already knows, so...
