First and foremost, let me say, I love basically everything about New Dikamazi. The people, the content, the culture, the scaling encounters, the quests, all of it (Even though that junkie took a petal from me for nothing!), but I'm very curious why the unique features in ND are time limited?
There's some absolutely golden stuff there that I feel would be wasted if it's just lost after the event is over. (I'm also unsure what exactly counts as "Unique Event Features" that will be leaving? The scaling? The Drops? The shops?
In any case, I feel that, instead of this being something new that eventually becomes "obsolete" (I use this in as neutral a term as I can, I am not saying that the area will be worthless without the event status, but just "moved past") that maybe instead, certain areas just work like this as an access to cultural drops and scaling equipment. You could make it sub-optimal compared to punching above your weight when hunting so it's not the "best" place, but these unique mechanics are something I feel should be encouraged, not just time limited.
