I would have three high-level fates that spawned under different conditions, each one dropping one item.
- This would stop instances from dying when Zuzu dies. People would stay and start focusing on the next one. By the time all three were dead, the cycle would start again for the newer arrivals.
- It would give high level players more to do, and they would bother less with the lower level fates leaving them for lower level players
- It would split up the NM train because you would have people in multiple areas prepping NMs.
I would also make it so that if you're for example 10 or more levels below a fate you don't get anything, or hardly anything. This would take some of the lower level players off the train and have them in groups doing the lower level NMs. I would also do it in reverse for like a lvl 20 player doing Cactaur, even synced.
I like Eureka, but SE needs to fix a few things one of which is the NM train. The other big one turn ins, which I have ideas for as well.
