»I have an idea for skyblock

Hello, its me LWHIRUS, i have an idea for the skyblock.
The idea its:A mob when is killed, the mob can drop the item it drops normally and the mob can drop other itensickaxes, Axes, Swords, Hoes.
These items have 4 classes: common, rare, epic and legendary.
Each rarity makes the item better or worse.
Thanks for read this :v

 

Then mob grinder chests would be filled with op items. Maybe they can add bosses again.
