I don't like paying DLC, they are a way to make a game more rentable when you should have already most of contents. Not to mention 60 bucks is already a heavy price to pay for most people and some don't want to have a psn/xbox/other online account.

Completely non-mandatory adds are ok (side bosses for example... broken endgame weapons, sidequests that goes into plot/characters' development are off-limits) Free DLC are perfectly fine (who would be against bug fixes ?).
