3 mc ideas

Idea 1:It would be great if in minecraft would be a hazelnut tree and if you would break leaves you would get hazelnuts.they coud be crushed in crusher so you could get crushed hazelnuts.you could eat them or craft something like hazelnut soup!
idea 2:
i would like that minecraft could have classes.for example: elf would have more movement speed,+bow dmg...
There would be a lot of classes.
idea 3:
There would be more NPCs that would give random quests (for example you must to clear a cave of mobs) you would get xp and stuff for completing.with xp you wouldnt use for enchanting but for having better classes (read idea above)
Hope you like that ideas :)
