Middle of the road on it, honestly. Have not done the Raid yet, but I quite like the Will of Crota Strike. In fact, it might be my favorite Strike in the game, so far. The weapons and gear that I have picked up so far all seem to be reasonable, in terms of a small move of the overall end goal. As to the Eris mechanic, it is absolutely awesome. Very similar to what I had recommended in my feedback thread. The fact that her quests intermingle between story missions, quest-based bounty objectives, and the Strike are actually a really wonderful thing. But the downside is that there just is still not enough of it. For House of Wolves, I would really like to see the Eris mechanic expanded. Not just one NPC, though - make it for multiple new NPCs, and also start integrating it with existing NPCs. They are missing a golden opportunity here. Speaker Quests, Cryptarch Quests, Shipwright Quests, Gunsmith Quests, etc. If they want to move to start making the dissatisfied populous of Destiny a bit more back towards the game, they would start rolling this mechanic out in that fashion, as soon as possible - and not just as a part of a DLC. So, I am not disappointed - but I am not thrilled, either. I've enjoyed what there was, so far. I may sway more towards positive, though, once I get to Raid.
