Which a large percentage of the time is utterly impossible if they flat don't want to fight you there.
Moreover a character can spend his entire life without encountering a single ranger and rarely entering wilderness zones if he wants... the only exception to this is all the $#^@ing rangers that make it so that you pretty much have no choice some days but to take a shot and ask one to group. Usually they are outlander or ranger so you're fucked either way, they'll find a remote excuse to kill you or blow you off to masturbate with their ranger buddies or go solo rank.
