Horrible interview. Here's my takeaway in TL;DR form... (Destiny)

Interviewer: Even though people play Destiny for hundreds of hours, everyone complains about it.
Luke: We are fully in touch with people's complaints.

Except, he didn't say that in the least. At one point he said: "I would say we are absolutely proud of what we’ve accomplished with Destiny, and where we’re headed. I think we’re really bullish about the future. But at the same time we acknowledge some of the things that need to be better. And that’s what we’re trying to do. And I think the critics, and many players, call us on those things. And we’re totally trying to address those."

Interviewer: Here's another complaint: The game introduces factions like the Awoken but never explains who they are or why they matter or any of that.
Luke: In 80 years, you'll remember the epic tale of how you got Gjallerhorn, but not who the Awoken are.

Yeah, that's one I wish he'd addressed better. Destiny's story, so far, hasn't been told in the same way but we still know a lot. And it does seem that they are trying to do more in-game story stuff with TTK. Bungie, so far, hasn't really admitted that the story needed a lot more, but they have spoken about it in an "around the edges" kind of way.

Interviewer: Why is there no plot in Destiny?
Luke: Mahyem is a good pvp mode.

No. That's completely ignoring what he actually said. Read the response again. It's not about Mayhem, it's about bringing more levity and story to the forefront of Destiny. He mentions story, he mentions Eris and Zavala. Only after he answers the question about the game taking itself too seriously while not having enough plot (again, the answer was TTK will have more levity and more plot) does he talk about how Mayhem is the gameplay version of that where not every mode has to be super competitive and can instead be crazy fun sometime too.

Interviewer: Destiny is really bad at things that Halo was good at, like the AI.
Luke: They're basically the same.

And they are. There's very little units in Halo do that they don't do in Destiny. And they do things in much the same way.

What Destiny lacks is some of the unit personality that Halo had. Units can be scared and run away in Destiny, they might even be more likely to do so or be triggered to do so when a leader unit is killed, but we don't see the obvious almost over-the-top reaction of the Grunts always running away when an Elite was killed. But put Elites, Brutes, Vandals, and Acolytes in the same room, swap their model and sounds for something generic, and give them the same gun and I think it would be at least somewhat difficult to tell who was who during most of a fight.
