Re: Everytime I look for an opponent it is the same person and they always leave!!!

If the player you are being teamed up with shows as the Titans then it is a connection issue.  You might try opening your ports if you haven't already.  It could also be their end.  The reason you would keep getting matched up with them is because you both search again right away and the system tries to find someone on the same level as you.  You were probably a close match and kept getting matched up due to that.  I've had this happen once or twice and simply waited a minute or so before searching so I would get someone else.
