I have all the DLC and I cannot get into a match with them… is there a way to narrow down players who have them so I don’t get into matches where people are playing and haven’t bought the DLC? I am very tired of playing the same maps over and over when I had payed my money for the DLC… :c
Best thing to do is try and party up with DLC owners, you can make a post in the Recruiting forums or maybe try a Spartan Company? Must be some Reach oriented companies out there 
Thank you very much for the informing answer! :3 I will take your advise and do some research.
