Since the latest update passive & hostile mob spawn rates have decreased from already low pre 1.14.3 to almost non-existent to 1.14.3. Wither farm/Ghast farming is impossible due to the spawn rates and the risk of a nether reset is offputting so no one wants to make more efficient farms since they're huge projects. Because mobs spawned from spawners are also not aggressive towards players making mob spawner farms also become excessively inefficient to make farms because they just clog up the systems. Fix please or offer an easier way of supplying these materials because waiting hours just to kill only 27 wither skeletons is way too grindy and just beginning to become unfun.
On Philia, we have guild vaults (Max 3 vaults). It's quite OP especially if you're in a one-person guild then you have 3 vaults all to yourself. It's incredibly useful, I use it all the time and it saves so much more time. Also on Philia, we don't have OPOP gear so I guess you can find yourself in a life or death situation and quickly put your items in there quite quickly. But I do agree - I only ever use it for temporary storage while mining & building. I can fill the vault with shulkers and pretty much have unlimited storage in my inventory.
I don't know if this still works but in old CC when you did /rankup buy it completely screwed your donor perks (lost perms to /fly etc) and set you back to the player ranks but you still had your donor prefix. Could try that if u wanna go back to basics. Dunno if its the same plugin on Lothar tho. + If you end up changing your mind staff will probs get lowkey annoyed. Use at your own risk. :P
