that’s already been discussed to death.
My question towards your suggestion is why would you think adding another map that is just like Niff 2 reduce player fatigue? If people are getting burned out of farming the same map over and over then they’ll get burned out of farming the same 2 maps over and over.
And that’s assuming we manage to get perfect balance between the 2 maps, which is close to impossible unless you copy niff 2 with same map, mobs and drops. Otherwise one will be better than the other and all players will flock to the one map that’s slightly better. That’s why everyone goes to niff2 in the first place so you aren’t fixing any problem.
No, the main problem is that Niff 2 is the most optimal farming spot : you get raw zeny from item boxes and player zeny from BB. And since BB is one of the most important late game resource if you’re full stuff you go there too.
So the solution isn’t to make more places like Niff 2, but to make Niff 2 less strong and dissociate zeny farming from BB farming, just like in mjolnir.
