Yeah, and recently while wearing the same amount of armor, a single arrow took 100% of my health, from medium range, archery is srs bsns.
It really depends on the arrcher build to be fair.
Again, some archers take the minimum PD, while others (Like me) squeeze it for every drop. It also matters quite a lot on the range. I can drop any mid to low level horse with a few hits (Or one well placed headhsot) at close, but have to hit the bugger a dozen times from long range.
Just like some twit can kill you with five swipes form a sword, and others are a STR build to the max and one shot you with the same weapon.
