It does seem like the loxes are more sensitive, but that may be due to being able to tame them now. I agree that it's not exactly realistic, but I wouldn't expect that with this type of game.

I find fulings the most realistic in their actions, although I don't understand how you can almost skim the top of their heads with arrows sometimes and they don't notice. Nor do they necessarily notice their buddy dropping dead in front of them!

They should also train them better to sound the alarm and not try to one-v-one when they do notice someone shooting at them.
