I thought it was (Destiny)

To me, Raids are fantastic, static experiences. An Arena in my mind would have more enemy variety and have periodic content updates. I can easily say an Arena will probably have a longer lifespan, so I'm totally okay with getting that now and having the Raid delayed a little.

There is a difference between a human hand designing the challenges you face, and a bunch of random enemies like in firefight. One is way better than the other, but might not be as 'fresh' for long.

If the Prison Of Elders is like the challenge mode from Vanquish for example, then you can sort of have the best of both: designed encounters with the variety and chaos of horde mode. Of course there were only six of them…
