Well I don't care about the hard difgiculty. If you want to live..... GET BETTER AT MINECRAFT... so yea all the hard difficulty is make mobs harder to kill which is perfectly fine. But I would like to also suggest that the bigger the lot the more mobs.
Well its not that it's hard to survive on hard difficulty, I'm talking more about setting up. If you were a new user, most of your first few months are spent in a hole on your lot, which is swarming with mobs. It's even harder since starting off, you have nothing, and you may not have any friends to call up to protect you.
I just remember when I was starting off I died a ton since I didn't have armor. I'll admit to being a noob, but seriously, too many new users are getting pummeled out there, and it makes them not want to come back.
