Layering in Stormwind?

I dont know about Org but SW is horrible during evening hours while a crapton of people are waiting for the buff to go out each night. Maybe it doesnt need to be every server but Pagle lag is horrendous in SW.

I guess the main issue could be (not sure though) is if SW was layered due to the lag, and someone dropped a head, would it apply to all layers?

yes.

Ok well thanks for the copy of the blue post. That pretty much answers my question.
