Anyway, Fujin0, I applaud your effort at trying to maintain an informative thread. Although your attempts to keep it pure, I believe are an excersise in futililty. People are going to post in the active threads no matter what you say.
What I would suggest is making a thread in the style of a guide — like one class per page, and another few pages on resereve for gear, quest updates and such. One could then make edits to the original pages as more info comes in on the PTR notes. That way, all the important information will be up front, and up to date, while still allowing for the usual forum jibber-jabber on the subsequent pages.
