For the final destination of everything the end isn’t very intimidating, I mean sure there’s a dragon but that’s still not a very big challenge for players that into PvE and once you do kill it you face neutral endermen that attack by themselves and teleporting boxes that can give you a useful levitation effect the end isn’t very hard at all the scariest thing is the void but shifting is all you need to do to not fall. I mean considering it’s the final destination in the game it isn’t difficult at all.
You’ll die more by a creeper than anything in the end.
Currently the only hazard in the end is falling into the void. I propose that there should be some way to mitigate (at least partially) the hazard of falling into the void, and add stronger and/or smarter enemies to compensate.
