So if he can't personally be there, Tiamat would no longer be a cause worthy for the Giants to fight? Why does he believe such a falacy?
I plan on following up my 'beefs' post with another one to help DMs prep for Hoard. I blame that "not quite right" feeling on the fact that so much about fifth edition was in flux when the adventure was being written.
I don't really have a horse in this race as I do not have the module and haven't read any of these articles (other than the initial one in the op) though I thoroughly enjoy your AD&D module reviews, @MerricB , so I am sure they are well written and thoughtful articles...but, I suppose my question here becomes, does not the fact there is a need for multiple series of articles on "advice" for the module indicate that the adventure is, in actuality, very poorly constructed?
Lending to the "legitimate beefs" side of things?
I'm on the player side of this adventure as I'm not DMing it. One of the things that annoyed our group was Beef #3: Dragon Eggs & Unclear Goals. I don't know if this is covered in the adventure or not.
We decided to take the eggs rather than destroy them. There seemed to be no guidance on this for the DM, and it turned into a genuine cluster f#. From that point on we have been just simply following the railroad as we got so frustrated with the situation.
