I think that lucky blocks should be changed to TNT. TNT currently doesn't really server any purpose to most players on the server. Meanwhile sponge has a use which at least some players use from time to time to drain areas in the ocean. If you are making an underwater base or guardian farm it is really inconvenient to have to fill every block by hand and destroy it again. If you don't want people just to craft TNT I am pretty sure you can disable the crafting recipe for it with plugins. Please leave your thoughts below and vote whether or not you think this is a good idea. One more thing, I think that lucky blocks should have a very small chance of dropping keys when opened.
