in factions why don't we add creeper eggs? its a good way break in to peoples places and will force people on factions to find a way to prevent people from getting in instead of just blocking chests. and its not hard to have the creeper eggs added. pretty easy installation
Probably because there's already /jump it would be really annoying trying to protect from both of those. The only way would be to make unclaimed bases and there's a lot of people that use X-ray texture packs and stuff like that.
what does /jump do? ive never seen it... if /jump is sort of like creeper eggs, then I guess that's why they don't have /fireball
