Two out of the 3 DLC's are rubbish.
Warden's Keep and Return to Ostagar both last 20 to 35 minutes, offer nothing of interest, except for a cheap retcon in RtO. 8€ for 1H of content is not really my view of caring about their fan base.

Then, there's how RtO's release was handled by Bioware. The DLC is delayed several times (which ain't a problem), appears on the downloadable content list, then disappear because it was bugged. People get mad, because they bought the DLC in good faith, which in turn made the game go FUBAR. When faced with this, Bioware decides to close all topics about RtO on its social website and to ban users who complained. Two weeks later, the DLC is released for Xbox360 and PC, and PS3 users get no news, until RtO was finally released for them a few days ago.
