My biggest concern with temp worlds is that I will never get to enjoy them.
Because of the time I play, I miss EVERYTHING.
I’m really going to hate it if I never get any of the limited time stuff besides rock. (I even see the trees being farmed away real quick.)
As for regions, multiple worlds at once is just silly. I see it more likely that they will cycle through the regions.
Hopefully they rotate the drop time as well. (Hook a fella up with a 10pm Pacific drop, huh?)
