I've noticed a lot more people discussing their plans to join Order on this forum and I thought I'd rally those prospective followers of Destruction.
This would be a good topic for those who intend to follow Destruction in OB and/or Release to advertise for guild/party/whatever.
And for those who haven't quite decided, but are still considering your options here is a small showcase of your Destruction options. (Granted these may not be the only classes, these are only what will most likely be in the OB, not sure about release and on)
