Just a heads up for those dragons who are anticipating joining the Lairshaper school. The Lairshaper trainer currently has one broken link, the one that would allow you to rejoin the school. So, if you join Lairshaper and then switch out of the school, you will not be able to switch back.
This will be fixed with the patch that is scheduled to go live at the end of the Lair Auctions (around the 29th).
