Given a battle between two armies H and A, which let's say start with the same number of soldiers, and given the fact that both sides will have some losses in terms of men, shouldn't the horde be able to gain 100% extra soldiers from Alliance and let's say from 50% to 75% from their own faction, just by raising undeads?
In a middle/long term scenario, won't the horde be able to overhang the alliance?
Am I missing anything?
