Why does the Fellowship of the Ring scenario last 4 to 6 rounds, and are battlegrounds 5 and 6 always needed?

Question

Accepted Answer

The scenario ends at path 6. Cards such as Gandalf the Grey and Strider can advance the path faster, so it can finish in about four rounds, and battlegrounds 5 and 6 are only used if the game gets that far.
