I say No to a new map because I have made some great builds and created a city with my friends. It would be a pain to have to regroup and rebuild the entire city and collect the resources again.
There aren’t very many updates in 1.4 that can’t be found if we kept the current map. Although Witch’s huts won’t appear, MCNSA will still be a great server for everyone to enjoy.
So I think when 1.4 comes to minecraft, we should keep the current map.
Say NO to a new map!
