Yeah sure, the story is simply a horde mode. But I'd like a dedicated horde mode. Take 2 others in with me or go alone. I will say however, if this hypothetical were introduced, I wouldn't want it to get hard quick. I'd want it to be massive, thousands of waves. But that last wave, well. You know. I want something to consume my time, after nightfalls and raids on my 3 characters, I have nothing to do but help friends do their nightfalls and raids. If I could spend two hours, get to wave 56, go to bed, wake up and resume, that would be fantastic. I want something that would take hours upon hours to do. Didn't I read that raids were supposed to take 4-10 hours? Well, I did crota today in about 25 minutes. Rewards don't even have to be great. Just give me something that's worth as far as I got to. There's infinite potential in this game, and while this might not even be a great idea, it's something I'd like to see implemented, as it's where most of my time would go.
