They will buy for strike, missions, new gear, and crucible maps. And for possibility to invite for Raid. Or maybe At least half of fire team must have DLC to participate in new Raid And for example in Gran Turismo all DLC Tracks can be played without buying when you are invited by someone who had this DLC. You couldn't play it in single player. Without that options. Why buying this DLC when i won't be able to play Raid with friends? Being charged for content you will probably never see because of player limitation isn't fair. I wan't to buy this DLC, but i don't see any sens in dividing community by this Raid. It will be impossible to play without Matchmaking.
