everyone wants nether to be much more harder! now is the time I think the devs should work on improving the nether, some options and suggestions that I would like mods and devs to hear r replacing keys with nether alters which can be ACTIVATED to open the nether exit…each one has a timer of 5 seconds to run away from since they detonate/explode, therefor killing anything nearby including mobs or actual players. after all 4 nether alters have been activated, u will see a path tracing to the exit portal, another suggestion is to add more mobs and a few traps shall be introduced such as nether wyverns which are monsters that can be found in the depths of nether and shoot beams or fire balls depending on how close you are standing to one. traps such as bear traps could be scattered to damage and slow down players but there are no damage over time effects. Finally, if you are a certain lvl (example: 100+, you will have to slay the boss of the nether, similarily to the psycho scientist in the lab to exit nether)
EDIT: so ima try to be more clear; depending on your level, the difficulty is chosen, therefore, if you are a starter, nether is gonna be basic and normal. now, if you are a well experienced player, nether is gonna become more challenging therefore, containing some stages aswell, if you are lvl 150 (MAX LVL) you will be allowed to choose the difficulty.
Please don’t make it harder, there are so many subjects who don’t even dare to do some nether. Just add another nether dungeon like level 2 red scroll.
Simply making it harder sounds more like a nerf than a buff.
I agree with @FarmMiner, there should be another harder nether, but one that is, unlike Deep Nether, also a means of getting Gems.
