Again, I'm with Fordhim on this one. The extra guards not only add further, adnperhaps too much, complexity, they also remove some of the urgency from the story. Already we have four groups:
- Lorien Envoy
- Mirkwood scouting party
- Main force of badies
- Elite Easterlings and Orcs
If you really desire a fifth point of view, surely ther are some non-warriors in Lorien. We could have brief looks from them about the waiting they must endure. They could also give a look at the mou nting tension in Lorien, as well as shock when the surprise force shows up.
