Chamber of Aspects *Realm

So i logged in late this evening, tried to log into my realm, Silvermoon, found it had been locked and had a queue of about 600 people all wanting to connect. Didnt seem so fussed about it, i took a quick 30mins rest to come come back and find i was still queueing for atleast another 20mins so i thought stuff it and decided to scour the other realms, i then came across Chamber of Aspects, is this a new pve realm blizzard have tried to sneak in with the expansion?
