My point is that if you had written that theory two years ago it would have gotten a lot of discussion and recognition; now, it's going to be seen by a smaller audience.

As for why I think it's a waste of Demandred, it's because he was built up too much as a genius bad guy. At this point, unless it turns out that Rand is Demandred, and Logain was the Dragon Reborn all along, his identity is almost certainly going to be a let-down and a wasted opportunity of a character.
