@DrSwank: If you "love" everything you've done so far then there is plenty more where that came from, so theoretically you might love the rest of the game. As others have noted though, be cautioned that the game doesn't evolve one iota from what you've been doing thus far. After level 20 you will be introduced to a great many new economies you will have to grind for but the basic gameplay remains unchanged, apart from the two raids. At this point though, apart from just seeing it, I don't really know what point there is to doing the Vault of Glass raid. Not only is the vendor armor better, but the unique perks on the raid set is VoG specific.
I really have enjoyed what I've played so far. I've never been a big "loot" guy, but the gameplay is fun.
Apart from everything else, the game on sale, without DG, is like $43 I think(?), from what I've read, most people feel like for $10, the Dark Below is worth it, which I presume that the follow wolves dlc should also be "worth" roughly the same, it seems like spending the extra $24 to get DG would make it a worthwhile purchase.
The sad part... I've spent more time (and had a better time) playing the Destiny trial than I did with Halo MCC... :(
