Overall: 500 points, 33 units, 6 might, magic, shelob!

I like it. There are specifics that I would change because of how I like to play, but this is your army list. Try it out and see what works and what doesn't.

"He who has the most Might at the game's end, wins."

Take Grishnak instead of a regular Orc Captain: 3 Might for the same price. Add a Might to your Nazgal, or consider the Witch King with 3 Might.

Grishnak isn't the same points as a regular Orc Captain.

So, what is the point of having so much might?

I mean, if there is a dragon, of course i wish he would have 30 not 3 might... But on a regular hero? Or a hero that is not a fighter? Perhaps an occasioanl heroic move? Nazgul can boost a spell... A courage test... Ok, many reasons, but still, would 2 points of might be worth to replace warg from captain (the mobility)?

My bad. Extra 5 points for an extra Might is worth it.

The ability to get a Heroic Move at game's end--when your opponent has run out--could easily be the winning move. To use a Might to get the Transfix spell as the Monster is ready to Hurl: key. Wargs die quickly. I suggest:

Witch King 3 Might 1 Fate
6 Mor Orc Shields
6 Orc Spears

Grisnak
6 Mor Orc Shields
6 Orc Spears

Gorbag
4 Mor Orc Shields
5 Orc Spears

Shelob (or trade her in for a truly formidable WK on Fell Beast: a Monster with Fly and 3 Might...and Black Numenorians replacing Mor Orcs)

500 points 9 Might 37 Units

So, what do you think ppl, which list is better: The one with 3 more might, but no cavalry at all, or the list with 6 cavalry unit and 1 cavalry hero, having still 6 might?
