They had ambushes. Remember all of the "paths of gold" that led deep into the woods? But you're right, they could make them even more exciting!
That was hardly an ambush because you had a little time to run away because they cam out of the trees to the north, am i right. so u could just run away o the south. without even getting hit once. larian could have made it better by having a small group of orcwarriors coming up from the south (on patrol <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" />) so they ran into u if u decided not to fight.
