Well, I was out adventuring in the wild, looking for enraged, and I started killing them, and also noticing the diamond drop rate for them has decreased? I have no clue, I haven't been getting diamonds as frequently as yesterday.. Also, I think looting now affects drop rates of Dragon Stone Fragments..
I kill about 3-6 enraged per night, get about 2 diamonds. The enraged creeper diamond drop rate has fallen. I'm getting better drop chances from enraged zombies, skeletons, ehhh there the same.
You better not have or I'll ban... wait that won't work banning the owner wouldn't be a smart move for ANY SERVER! Plus you could probably code yourself back in anyways! Diamonds drop for me... Even when they've just killed goldenappple12345...
