WOW uses a subscription model. Destiny is outright paid game, with DLC on top. Its just the shooter fanbase aka FPS players won't stand for it. We can just -blam!- off and play battlefield/cod/whatever else that is just XP based, playing other real players, and leaving strikes/raids to mmo crowd. Because after you've done a strike a few times, really its just repetitive grind, with enemies spawning in the same places over and over again. And for what, just to get the shit you've just earned made obsolete every three months. Im sorry but repeating vault of glass for random raid gear was stupid enough the first time round. Seriously the developers milked each level over and over, then -blam!-ed you again with DLC. Thats said if Bungie makes Destiny a true MMO, with a massive expansive universe to go bug hunting on a far far away planet, where you don't care about the V.O.G because you so busy lost in some far corner of the universe doing your own thing, that be great. But its not going to happen anytime soon.
