Poll: Reset the map?

[yottabyte]

Horses are able to spawn, indeed. But it's very rare that new animals spawn in existing chunks. Then you have to consider that horses only spawn in plains, and having horses spawn in plains is also rare. Then you consider that donkeys are even rarer. Sure, it would work in the long run as people can breed horses and donkeys eventually. I guess we can also add in some crafting recipe for horse armor. But it would be easier to just reset the map. I guess that's the general idea here.
