You and me both. Dragon Age and Mass Effect 2 are some of my most enjoyable purchases from the last eight or so months, yet their DLC offerings have been very meh all around. Even the delightfuly creative "Darkspawn Chronicles" for Dragon Age didn't offer much beyond a short gimmick. Which is sad. Bioware makes great games, but thus far terrible DLC.
If the DLC is actually meaningful (more than an hours content) I think it could be very good. Otherwise I may stay clear.
