I joined after WotLK came out so I have not experienced a beta phase before. I have been reading posts about the changes since they first started coming out, but many of the things I read about have already been scrapped or altered.
Rather than confuse myself with information that might not end up live I'd like to wait until the changes have 'stabilised' - i.e. major stuff has been decided and only the details need to be worked out.
When will this happen, if ever? Should I wait with 'serious' research until the expansion has actually gone live, or is there a point beforehand from when I can start making inroads into the new information?
In case it's relevant: I have not opted in to the beta and have no intention to do so.
