Look, we were promised an expansion. What do we get? A strike and the like. With a raid. Woohoo. BUT, DLC is always adding on to a game. Nothing was taken away from the game; the spotlight has simply changed from the vanilla game to TDB. While I'm aware that the weeklies/daily/nightfall will be rotated every week with the regulars, next week it'll be normal again. Leech it as much as you want. Argue away.
