In terms of mobs I don't see enough to call it a survival world. I think the mobs need to be increased, and I thought zombies broke through wooden doors, but the doors just reset.

From a setting of 0-3, we are set at difficulty 2, same as before. As far as mob spawning, it is at the default rate for MC, which is a setting of 70.  On the old world we had increased it to 125 when they were messing with the spawn rates.  I set it back for now because as we were building, it seemed they were already spawning excessively.  If after a little bit it seems too easy, I would certainly increase it back up to our old rate of 125. You guys can give me feedback to how you think it is in the next few weeks and we'll go from there!  Thanks!!
