We're going to have to do enough changes as it is, so I'm wondering why people think it's worth removing.Remove all armor
Remove ALL TEH MAGICKS
No other dimensions, hostile and neutral mobs removed except creepers, wolves and (possibly) silverfish
Remove all armor: I can see this, but only if Tier 1 comes pretty much at the same time as Tier 0, so that it's really not that different.
Remove all magic: Again, why remove something that's already there? We could just change how entering the nether works, rather than, yknow, deleting it. Same goes for enchanting and potions. Maybe make them further along the tech tree? A branch of magecraft? The End, I agree with.
Remove all hostile and neutral mobs: What the actual crap? WHY? WHY? Somebody, please please explain the reasoning behind that.
