I love the new XP system personally. No more of “playing” minecraft while sitting idle for hours on end.
I’m very word about testificates being griefed though. Emerald ore is incredibly rare and trading will be the only way to obtain it. Maybe we could have a trading area at spawn of some sorts, with moderator spawned and protected testificates? Though, I think it would be better if you come across a village, you can /modreq it and there would be protections placed on it. Does World Guard allow for protections on killing certain mobs?
