The problem im running in to during this whole debate is value. I would argue that TDB and HOW both consisting of largely reused content were not worth 20$ a piece. Basically we paid for what we already had. With TTK we have no real information to base overall value on. Bungie can say is the size of TDB and HOW all they want to but realistically that's not saying alot based on the actual amount of new content that we got with the previous two dlcs.
