more bosses and enemy's

I think that in Minecraft we could do with more structure's and more bosses to make the game more fun like a samurai Illager boss that would spawn in a Japanese temple in the lower levels of the temple there would be armored pillagers once you defeat the samurai Illager it would drop its katana we could also have a ruined castle with would be the home to the lich boss witch would summon soul fire and soul fire wisps to help it fight the player and the boss would drop its staff which would allow you to summon its soul fire wisps to fight mobs another boss that could be added is Illager wizard that would spawn in a wizards tower and it would have many Illagers in each floor and this dosen't have to only be bosses we could have a pirate ship full of pirate Illagers and a pirate captain the amethyst geode could have an amethyst protector witch spawns with a 5% chance to be in any geode there could also be a more rare stronger drowned another mob are spear holders which use craftable spears to attack you there could also be more passive mobs like the liveing mushrooms,the owl,rats,flamingos,and the giant beetle witch will only attack if the player destroys its home and lastly we could get a ender dragon set witch would be better then neitherit or we could get some form of ore in the end.
