Since population are declining at a fast rate here in MOP ( Frostwolf ) and finding a match or dungeon or raid is becomming harder. May I suggest an "Information Announcement System" where players will be informed that there are people queing for 2v2, 3v3, 5v5 or Raid Finder and BG's via a Channel. This way players will be more informed about the current status of the game. They will be able to know when to que or where to que in case of Raid Finder.
Some of you may have already seen this type of system I am the suggesting on "I dare not say the name of the private server". I find this type of system quite convenient like others do too.
For Example : When some people que for 3v3 arenas, players i.e both Horde and Alliance will be notified through a Channel, let it be Global or whatever.
Finding an opponent would also be much easier, and will reduce the amount of time spent on queuing for a match or a dungeon.
