Too bad that dead eye assassins Legolas and/or Tauriel weren't at Helm's Deep when Saruman's forces attacked...as surely with at least one of them present, no torchbearing orc could have reached the culvert.
And in Hobbit 2: DoS, why didn't Legolas put an arrow into Bolg's head upon site? Why did the blonde one feel the need to go sword-to-sword with this larger than normal orc?
