An army could have 500 units, and they could be 500 poor choices, there has to be more that just quantity.
Though quantity does increase the chance of being able to abusively list tailor - you mention in your original post that it is difficult to list tailor against a huge faction, and by the same token a huge faction probably has multiple units that can all fit in a sweet-spot against a known opponent while performing different tasks.
