If it was a joke, great job Warmane.

The "rdf" icon u see down there was implemented in TBC it just wasn't called dungeon finder but looking for raid. The interface existed then and was implemented to remove the old "Looking for Group" channel that was used as a mechanism in vanilla to make pugs. So yeah both of u are wrong and what u saw doesn't prove anything since if u take a look at the sun/moon icon near minimap and if u see the missing achievement icon u can be sure the videos are made on a tbc client and a tbc server ;)
