You can't run away from a troll? Wow.

Your play experience is much different from mine. The first troll took a while to kill, but it certainly didn't take 3 hours of shooting a rock; I think I spent a full night plinking wooden arrows at a freestanding wall section in my house but otherwise no special training at all. (pro tip; you don't have to draw all the way back to get exp, so you can get in a LOT of arrows in one night.)

I'm sorry you didn't like it.

BTW, I think I should draw your attention to two words; Early Access.
