Bungie Employee Info on Alternative Ending

[Scatcycle]

So Otto said this:

Will we get a little extra something by beating the game on Legendary?

Yes. Two things.
1. You get the achievement, "A Monument to All Your Sins".
2. The last level "Lone Wolf" is much harder and the enemy wave configuration differs slightly from the Heroic version.

Sorry. That's it. If you don't believe me, beat the game on legendary and watch for yourself. I'm not sure why there is so much heated controversy over this issue since you can easily verify it yourself.

Now this is interesting. First, this doesn't disprove the alternate ending, because he said "No, you won't get anything other than these two things for beating it on legendary". 

I assume the alternative ending requires something more complex.
This is what intrigues me:
"2. The last level "Lone Wolf" is much harder and the enemy wave configuration differs slightly from the Heroic version."

Wave configuration differs? Could this mean that Field Marshalls are in the Lone Wolf level?
There is something fishy here...

I suggest we try to last as long as we can legendary lone wolf. We need to find a place where the covenant come at us one at a time, so we can kill them. Letting them sit there makes it so no other covenant can spawn, so the next wave will not hit.

Anyone with me?

I don't see anything fishy there, it simply states that Lone Wolf is harder and has [harder] different waves. Sorry.

Well, what I see it as is that By playing the game on legendary in one go makes Lone Wolf harded than starting there on Legendary. Just my 2 cents.

Why would he say the same thing twice in one sentence?

It not the same thing, I guess. I mean the enemies are of course harder on Legendary, but aside that, the waves are harder, too.

Other then the enemies of the waves dealing more damage, how much "harder" could it get? It goes elites to elite generals.

Maybe the strategies they use are different?  Maybe more enemies appear?  There are a lot of things that can make it harder, other than just amping up their health bars and damage output.
