if I could take away two features of Minecraft away it would probably be wandering traders and phantoms.
Wandering traders require emeralds and usually sell stuff that’s fairly easy to obtain. In early game you won’t have enough emeralds, in late game you’ll have everything they have to offer.
And phantoms harassing me whenever I come out of a mine after an hour of mining is just annoying. The only useful things are phantom membranes, because they can repair elytras… But I never even do fights with Ender Dragon so I don’t care about elytras that much
