Hunting would be a rather neat thing but I feel as if It shouldn't be something to add to the nexus, as the nexus in a whole is already a kinda burdon to the once more rp than grinding for pvp crafts server, I think it's not needed to make hunting a profession as it just turns it into a game more than roleplay, when its left to the ET to do the whole event thats when it becomes more rp for a party rather than hunting down animals with fancy plugins, though it's a neat idea.
As for bosses I believe that it would be a cool addition to the whole dungeon craft except for the fact that it would all be pvp related, a lot of the time mages would be nullified and any rp at all would be nullified, my view for that whole kind of plugin would be just a hack and slash at a confined mob with a lot of hp and then getting some cool pvp gear as a drop, turning it more into some minecraft mmorpg really..
Tldr: Stop substituting Roleplay with Minecraft Plugins
