I think minecraft should add new mobs like maybe a new friendly villager mob or something cool. But, also different maybe new enchants or more blocks but i think they need to add ne friendly mobs and enemy mobs maybe like a enemy mob that lives in the water like a fish or a friendly mob like a villager but also different at the same time maybe a new type or weapons and tools like obsidian or wooden armor stone armor i think they need to add to break mobspawners beause i find alot in multiplayer but i cant move it because im not admin or anything so its alot harder. Maybe emerald tools and armor and add maybe like with sand like soulsand but spawns in maybe swamp biomes like a sand that slows u but its not in the nether. Maybe add like a new type of redstone item maybe like a piston that pushes multiple blocks add more ideas in the comments
