What is the enhancement in mind? How should it look and feel?
Ok, I have a community that is currently making an MMORPG server on a massive scale, reason I was wanting WG support was because it would allow us to spawn only certain types of these creeps in certain areas. We want it to have some sort of basic progression like being able to move from one zone with 1 type of creep to move to another with another type, thats why I was wondering if that would be planned. Now this idea would not just go with my server, it could go with many others like ones that want Ultra Hard survival but want to disable a certain creep in an area. As far as I know, this would be the first plugin with mobs to support spawning in regions which would make it unique.

Please provide any additional information below.
