I think that you should have a 50% chance of getting a spawner with a creeper egg in claimed land.If you are in claimed land there is no way of getting spawners, this would make it so you had a chance to get the spawners.
Bologne, even though I hate you, I agree, its sorta not fair that you have to "over claim" someone to take the spawners. Like come on, then theres no point in raiding.
Well i blow it up even if it doesn't drop just so they don't get to keep it,I'm just saying that it would make raiding better,and there are many ways to protecting your spawners from ceggs
