So - HD is coming next week and we get huge class revamp. Old class guides are under Pre-HD Classes. Those threads are mostly going to be outdated when HD launches, but might be useful for remaking some of the new guides and at least offer wiew to the history.
Other than that one sub-forum, this forum has sub-forums for each class and the info is based on HD beta and to be updated as HD is out if changes are coming.
Reason we now have sub-forums is to prevent long threads, now you can ask questions in your own, separate thread or discuss gear and skills separately. Easier to read a categorized forum compared to extra long rant of discussion, gear examples and skill rotations on the same thread.
General discussion - like line of sight and group roles for example, can be in the main classes forum so they can be easy to access to by all players.
