what im suggesting may be a little controversial

im suggesting a rework to the siege and cannon pluggins
the rework would be all blocks are breakable in siege but only by the right projectile in cannons

heres a list of projectiles and what they break

sponges-water
cobblestone-stonebricks cobblestone and any stone type blocks such as deepslate andesite stonebricks netherrack
tnt-sand dirt coursedirt grass mycelium podzul gravel
diamonds-obsidian
ice-lava(turns it to stone)
firecharge- wool wood and snow

Certain blocks can be destroyed by anything such as glass glowstone and so on

i realize this would be a big change and players may disagree with it
i also realize that players would no longer be completely safe from raids but i do think if this is combined with some other changes such as hunger during a siege and builders able to build in siege but i think this could be a overall good change as the way piratecraft is mainly played is not very pirate like as hardly anyone raids and most people just hide in their raid proof base underground
