Warlords of Draenor: Group Finder 6.0
According to the latest blue posts about Warlords of Draenor, they are planning a new Group Finder 6.0 .
From the details, it looks to be a basic clone of oQueue.
See MMO-Champion for Details
I think this sums it up nicely
We're not trying to "kill oQueue"; in fact, a lot of us use it ourselves. We just think that cross-realm group finding should really be part of the core game.
I am excited for an integrated oQueue like feature - hopefully they do it right. I'd hate to see it end up like voice chat.
