I think it could be a good oppertunity to wipe the server , as it might seem more appealing to new people , the reason I say that is they might feel as if there on the same page as everyone else , it would also benefeit the community as due to the new features coming in 4.5 it may give people somthing to work towards
but thats my opinion , and I also can see why people dont want the economy to wipe tho , as it has been half a year so some people may not like having to restart their progress ,
