Adding a blast hoe, to for instance the next crate, would allow not only for the server to make more money, off selling keys, but also allow players to save time when harvesting large farms. For example, a fortune V, Spread (Blast) I hoe, would be worse in total efficiency, yet save time for the players. This means that players that do end up harvesting all of it manually will still be rewarded, as something such as the Tropical Hoe would out fortune it. However players that did wish to save time in harvesting, could use Spread (Blast) hoes to save time.
the only issue with this is blast and fortune don't work together. like the fortune works for the 1 block u hit, but it wont work for the other 8. hence why the spooky pick doesn't give the most diamonds for ores.
Currently, Custom enchantments will stay how they are and will not go onto any new tools, this is due to performance issues with our custom enchantments plugin which we’re hardly working on recreating with more benefit to the server side of things. If we do eventually have custom enchantments like Blast supported for such a tool, I’m sure it might be a good idea but we’ll see.
