Dwarves have very good courage values and a captain can make them stand fast.
Yes it is true that Dwarves rarely run anyway on Broken tests, but the combination of Ringwraiths and a terror heavy army will still cause problems even for Dwarves. I feel like just the simple addition of one Shieldbearer fixes this potential issue to make an all around list.

This is true, but that is why I say placement is key. You want the shield bearer going against one wound average warriors 1v1 (even if the enemy has spear support) so that he can cut through them and cause the enemy to break lines. I certainly would never send him against a hero. Also if you use Men of Dale or Erebor Dwarves as support + a banner so that you can use Piercing Strike with less risk, you can increase the odds of killing.
I agree that Might/Will/Fate is precious though and I will agree that if your list is already short on that, then adding a Shieldbearer is probably not a good idea
