Look at it this way.

He was clearly starting to stall in his later books, taking so long to get them out, and instead of starting to wrap up the storyline, he started introducing new elements.

I understand why he hasn’t moved forward, but I’ve lost all interest in ever picking up another book of his. The terrible writing by D&D certainly didn’t help.

My feelings of frustration are valid and my criticism is not unfounded.

I do appreciate your thoughtful response, thank you
