Is it possible to change the block breaking speeds? Slabs are like breaking obsidian, Haste 2 has no affect on breaking times... a lil bit painful to use your blocks massively if you need to take forever to change blocks out.

What version are you on?

1.21.4-0.5.3

Currently working with the diorite brick slabs and they break super slowly... even with a H2 beacon setup

Oh, if it makes a difference... the Fabric version
