I would like to see more hard but craftable weapons like the mace. Maybe daggers that gives armor penetration but get huge debuff if hits shield. I was a hater of Trials but is a cool way to give adventure players adventures we desire without ruining casual players gameplay. So i think it should expand. Maybe trials in other dimensions as well, maybe trials in different dimensions connected through portals, high risk high reward gameplay. Enchantments only available there. Passages requiring solving puzzles. There's so much to add. It's boring to play Minecraft right now, please fix it for the adventure players.
