Heya survival !
I might be a bit late on this, but I propose to remove mob heads from fishing “shake” loot in S4 (can be easily done in under a minute by changing the mcmmo fishing treasures config).
Removing Zombie/Skeleton/Creeper heads from mcmmo drops would reintroduce a few more interesting rare and difficult to get items to the server.
In my opinion one of the coolest things in survival is having a rare item and it adds a fun endgame task, when you’ve gotten bored of making netherite beacons and diamond pyramids.
Right now aside from crate items there aren’t a lot of truly rare or challenging to get items and the decorative value of having a stack of zombie heads isn’t exactly stellar. So I think this change would only be beneficial for the server.
Let me know what you think !
