Yes, of course the main goal should be to adapt to every single encounter you have. But in the wild world of dominions things can change very, very fast. It may appear that the enemy builds only one or two types of units, or that his SC is vulnerable to poison and frost, but that might be very wrong with a good player. Suddenly you face and invisible army of shadows and ghosts backed up with a SC who is frost and poison resistant when your army is focused on defeating just the opposite.

It that and many similar situations it is good to not have adapted too much to what you think is right but instead on avoiding the worst case scenario. A dynamic army with a balance between flexibility and focus can do that.
