I was looking up the rules of Mass Combat and noticed that even with the Errata presented in these forums the system is still a bit broken.
It works fine for Units of Size 4-10, but Sizes greater than 15 produce odd results. For example: a Size 18 Dwarf unit with Strenght 7 and Toughness 8 confronts a Size 20 Orc unit with Strenght 6 and Toughness 5.
If the Dwarves attack first, they do (Size + Str) = 25 damage. The Orc unit soaks 5 of this damage for a total 20 damage, being utterly annihilated.
If the Orcs attack first, they do (Size + Str) = 26 damage. The Dwarves soak 8 damage and take 18, and are destroyed.
I can easily see this problem add up as unit's Size continue to grow. The Battle for Pellenor Field certainly had units of Size 25, 30 or even 50 at a time. So, how not to turn mass combat into an all-or-nothing affair? Do I break large units into smaller ones? What is the biggest manageable Size for a given Unit? Are there better, more streamlined rules in that second Map Set?
