You paid for DLC which never had anything guaranteed in it and look at other MMOs like WoW you don't get a raid every 3 - 4 months you get one one every year if that Star Wars TOR and WoW went over a year with out Raids and the Dark Below content is only a few months old. Also the new game mode arena is for you know the 80% of players or so that don't raid. Which quite frankly are more important than the 20% that do. I raid all the time but I understand that doing a new raid every 4 months is something that is crazy hard and I have yet to see a studio pull off!
