Then again, we don't know how lawful such a transfer of power would be, especially in the context of the istari mission, nor is the relation between the nazgul & Sauron comparable to that between Gandalf and Frodo. Plus, Sauron learned a lot of sorcery from Morgoth, while the subject apparently presented little interest to Olorin.

If the Witch-King here is allowed to reveal himself briefly, it is logical to assume that at all other times he is required to conceal himself.

Then again, this happened in June, before secrecy was no longer required.

Finally, the letter simply does not say that Sauron gave the Witch-King "added demonic force." What it does say is that Sauron gave the Witch-King command of his army, from which he receives "an added demonic force."

You are twisting the phrase:

There, put in command by Sauron, he is given an added demonic force.

Nowhere does it say that from the command of his army he receives an added demonic force. You are adding your own words.

However, these instances still don't require the Witch-King unleashing his full force, just enough so he could get the job done (as his task was still to look for the Ring).

I disagree. Getting the ring was far more important than anything else for Sauron, and the WK was dismayed at the threats he received from his master, together with the order to abandon secrecy.

Those are small glimpses, little snippets, of the Witch-King's command role.

Well, these "snippets" come from some of the most authoritative sources, including the author. In fact, he comes off more as a leader of armies in those "snippets" than here, where he is a singular figure, wielding his sword in flames. These are the image and actions of WK as a demonic power, never before seen by the reader at such a level.
