To be fair about the trollocs, one-four is a match for an average man on his toes. A well trained, disciplined, and clever man could probably take on more... provided he's not overwhelmed.... meaning completely surrounded and getting attacked at all directions at overlapping frequencies, Or cornered, or has an endless supply charging him through a poorly defended doorway.

What is an overlapping frequency? Look at Assassin's Creed, and notice how the enemy constant takes turns attacking you. It's definitely not that.
