They work for me, but I have never used them as written. Like Iuz never took over nearly as much of Oerth as he did according to TSR. I can only guess TSR forgot how kick butt just their NPC's in the setting are/were...
You realise its happened at least one before right?Mystra die? Yeah, right. Like that could even happen. The Archmage of all time and space killable? What nonsense.

Some people may think that if a metaplot doesn't change things, then there was no point to it. That may be true, but there's a difference between change (Imperium breaks up into domains, borders shift around the Solomani Sphere, loss of Corridor to Vargr cuts Deneb off from Capital) and taking it out behind the shed and shooting it to death (TNE).
That's a good point. Many authors, especially novel authors, seem unable to think small, and mistake "world changing!" for "exciting", replacing plot and character and new ideas with trite apocalypses and other "Realm Shaking Events".
A bad idea or adventure doesn't get better if it's spread out on the entire setting.
