Why would you take the massive ogre/troll(I forget what they are) seriously considering the big beasts where taken down by a small band? Well there is a reason aragon, legolas, and gimeli are part of the good guys special ops squad, because they are fucking badasses. I think it's pretty obvious that without those three some help from wizards, unnatural beings, and other kingdoms besides the one being attacked the whole fucking world would be doomed by the ridiculously stupid orcs.
