I dont know if its anything that we can change but yesterday while I was camping the chest tree just outside of the cornucopia, with full iron armor and sword along with two enderpearls, I was waiting for the cornucopia to refill and when it did a guy started rushing it, i could see he didn't have much on him so i was gonna use and enderpearl to swoop in and ambush him. Unfortunately my enderpearl hit a spectator who was watching me from the air right in front of me and I dropped from where he was and died upon impact. Kind of a lame end to a well played game on my part.
