Hmmm... The above listed magical nonsense seems pretty intense for "normal" play and might be scenario driven only. The nastiest stuff in the Glottkin book is reserved for the scenarios and I can't see it being too much different for the 3rd chapter of the End Times. Either way, the story is excellent and I'll be picking up a copy when it hits the stores. As for the GT's... I have faith that the assorted TO's who run things have enough skill to figure out what will work and what will damage the scene.
After being part of this sub-culture for nearly most of my life I think I can say, without qualifiers, that table-top games are a reasonably bright bunch... The assorted communities will figure something out. They might flame each other for a couple weeks/months but something will be hashed out between the camps and the game will go on kicking for as long as people have interest.
