Hello, I have seen a some posts on back fills on previous maps. As stated in streams many times back fills reduce the animals allowed on maps which would reduce the chances of someone trying to grind for the GO since there is so many animals allowed per map.
I personally would rather have a new map with new species than the time it would take for back fills to be done. I am hoping there could be a survey on the subject from EW, and perhaps people could voice their opinions here on discord in regards to the matter.
