Endless waves endgame content

Yes, first post, hi all.

So my wife and I have been playing a while and the discussion of end game content has come up. One of the ideas we have had has been an area to fight endless waves of enemies (or 100 waves either/or). We figured it would be a nice addition to what is already available, or even something for D4.

Rifts present their own kind of challenge, but this would be something a little different. The challenge would be in seeing just how far you could get.

We understand that there would be some issues the devs would need to figure out, loot system for example. (Does loot drop normally, do you get a chest with rewards based on how far you progressed, etc.)

There is a lot more we’ve discussed and thought about, but I want to try to keep this short. Thoughts?

We had this before. It was called the ‘trials’, the higher you got the higher level GR key you got. This would be ok, but for me on HardCore it just doesn’t have a place in that game mode.
