What a terrible comparison. In MMOs you can get upgraded gear 5x in an evening. You get new crap all the time during the butt load of content you are playing through. None of them are special because they are replaced in 20 min with another that is slightly better. It works because there is so much to do. In destiny you repeat the same thing 100s of times for the gear. The gameplay is great but it's the same thing. If the guns aren't worth the grind then is it worth playing Crota 100 times for a black hammer or whatever item you want? Would you really care to do all that just to use a certain auto rifle a few times before the new one comes out? I wouldn't...
