Bungie already said those place holder levels will change. Bungie also said better gear and weapons are coming out with each DLC. Better gear obviously means higher light. Also I know about the damage scaling. If you did not know those place holder levels where supposed to be released on day 1 with the game but they held them out to use as DLC. So yes on the disc they have low levels but now they're being used as DLC the levels will be raised.
