You read the op? You know what the repect I had for has raised from -50 to 50. Also mentioned how the current state of horse riding didn't bother you. Could you elaborate on that? Maybe you are seeing something that I don't.
Sure. The main points you made were the lack of pivoting and the difficulty of hitting things with a weapon. It is much simpler after you find a good way to fight. The easiest and most strategic way I've discovered isn't to different from real life. Simply hold down rt for a power attack, and gallop towards your enemy. When they're in range of your sword while you're running past them, strike. Runn past them, turn around and repeat. Works great, and your horse won't get hurt as often. Trying to fight an enemy on horseback without constantly moving is a bad idea, mainly because your horse is getting hit, but also because if you're using a one handed sword, your range will seem shorter than normal, as you're on a horse. Hit and run tactics. Medieval drive by. Accept we stay til the job is done.
For arrows, its pretty much the same thing, accept you just make sure you keep your distance, and your enemy is relatively in front of you so you can see. This will be much easier depending on your archery skill level and if you have the slow motion aiming perk. And depending on your level, arrows will actually auto aim somewhat on your enemy if you shot near it.
Horse riding is a bit weird to get used to at first, which is fine as you are controlling a horse while trying to fight, so it makes sense. But once you get used to it and learn a few tricks of the trade, it is very useful and very deadly.
