Ever since slabs were introduced in Classic, they acted like stone. No player knew this until Beta 1.3, with the addition of Wooden Slabs and Sandstone Slabs, which acted like Stone Slabs. Thank goodness, Wooden Slabs now act like wood, but the Sandstone and Quartz Slabs have remained unchanged. They both have longer mining times than their full block and stair counterparts. The slabs have a blast resistance of 30, while the full block and the stairs have a blast resistance of 4. It's creepy for me, so can this bug or likely unintentional feature be changed or fixed?
Steps To Fix:
1. Go to Minecraft's code.
2. Make Sandstone and Quartz Slabs a different block (like how Wooden Slabs are separate blocks).
3. When doing this, change the mining times of both slabs to the same as their full block versions. Also, change the blast resistance from 30 to 4.
4. Change the block obtained by crafting them. Instead of the current ones, the Sandstone or Quartz Slabs will be the new ones.
