I usually go for 8 athletics with little to no armor, because then I can just about dodge any attacks if I concentrate enough. I don't put any points into charisma, and just grab any weapons I can. Also, I usually use just bows and arrows, with a fast weapon like an Arming sword or Scimitar for quick attacks, but that doesn't usually matter because I can easily outpace most enemies with the high athletics.
The only problem is if I set the battle slider to the right- I have to guerilla on the enemies and that takes ages to get through.
ESPECIALLY war parties with groups of over 100. That is not pretty at all. Also, I tend to pour the rest of my points in Strength and power draw, as well as Iron Flesh.
Enemy projectiles can be dodged, but sometimes I get too caught up and Iron Flesh is my sort of fall back plan. It's incredibly insane to be moving so fast that the enemies can't make a good attack on you. Side steps dodge vertical attacks, horizontal attacks you can just run forward full speed and you can out maneuver it, stabs are like vertical attacks. I usually am not hit, but there's rare instances. Dodging horses is also simple, some times I can even catch up if they slow down a little.
Sometimes I even go full archery, with 3 large bags of arrows and a longbow, and just dodge appropriately. Shield enemies aren't a trouble because I can shoot faster than they can attack, and even if they attack, I can just dodge it.
I usually don't use a horse, because I kinda prefer staying on foot. Aiming on a horse just feels weird, plus I didn't put points into Horse Archery...
