The should add an extra's update where they add some stuff like ____ Block, into a slab or stairs or fence, it would be a like a quality of life update but still give off the minecraft feeling

More drinks in Java edition 1.20
And, More food update in 1.20 (my opinion)!

i would add a sword that breaks shields or only parries like a shield, but needing to time when you block instead of being able to block forever. it would make shields more of a choice and not a requirement, it also would make swords viable again, instead of having to carry a axe to break a shield and shit.

but if it were anything, not a block/item. it would be to be able to attack with a axe in the off hand. thats it.
