Initially I was furious upon hearing it, but now I've accepted that it more or less makes sense and will be good.
However, I did have this scenario in mind.
Let's say the Nerevarine never comes back, Dagoth Ur wins. Landfall still occurs when the people lose love for Vivec, and Voryn Dagoth and his kin are destroyed by... explosion and eruption. What use is the Nerevarine, then?. In my mind, the Nerevarine is made not even important, since Dagoth Ur was gonna off himself anyways. This is the main reason for why I am uncomfortable, that the Nerevarine's tasks have been made trivial.
Hopefully you hear at some point that Nerevar made a triumphant return and kicked those filthy lizards back into the puke pits from whence they came.
I'm fairly sure I won't ever play through morrowind again as the Nerevarine, because... what's the point?
The Nerevarine's actions saved Tamriel, not just Morrowind.
Mind you, he/she was only ever just a pawn of Azura anyway.
This whole Morrowind Destruction has got me interested into TES Lore again after I lost it all after playing Oblivion. I might even buy the book. I'm not mad about Morrowind being destroyed much, sometimes the most powerful story is told when the thing you love is taken away from you. Morrowind's coolness kinda ended after the events of TESIII anyway, after the end of the temple. Just so long as that rock didn't commit genocide on the dunmer when it hit ground zero, I'm totally cool with it. It's not like we didn't know it was going to happen anyway, ala
Love Letter.
In fact, this destruction preserves Morrowind from the greatest evil of all. Bethesda's meddling. Better to die now in glory than die later in shame.
