Pixelmon Harmony seems quite a bit laid back, I would personally like to see some Envoys like you'd see in factions servers spawn around spawn, or pvparena if it gets expanded anytime soon. Envoys would be an OK addition because after a while, you end up not doing much. Half of the time I end up aimlessly running around the map waiting for a legendary to spawn. It gets boring after a while, and I feel like envoys with some OK rewards would spice gameplay up a little bit. A reason why you may not add it, however, is because it focuses more on the PvP aspect of minecraft, not "peaceful" and in "harmony."
