I've had my Titan, Hunter, and Warlock at level 32 for a month or so now and finally got my last exotic last week. Now with all raid weapons, besides Fatebringer which just refuses to drop, and all exotics I can comfortably put this game down for a while and play Bloodborne without the itch.
For anyone that really puts the end game time in it is a very enjoyable game. Although it has many flaws with the RNG system and the amount of content available, its still an awesome game especially with friends.
For me House of Wolves is make or break. I need enough content to keep playing until comet, and decent content at that. The raid definitely needs to be different in HoW as well. The fact that I can go into Crotas End normal mode and comfortably solo the whole entire raid is just stupid. Don't even get me started on Hard Mode and its glitches. Vault of Glass will still always be awesome.
