SOE has issued an upcoming content schedule that includes "major performance upgrades" and the introduction of mentor stones. Said stones will be placed at the entrance to all of Vanguard's dungeons in order to give players the option to set their levels appropriately.
The update post also touches on the Cave of Wonders raid content, which SOE says is now slated to go live via four separate installments. There's more on the schedule, too, but you'll need to head to Vanguard's official website to read it all!
