I was smashing my head against my keyboard because of frustration... I looked up to see Planet Minecraft in the recommended... And from that day I have decided that smashing my head against my keyboard always gives you answers.
I mean, updating the nether has been on my mind for a bit now, but the caves really do need spicing up. In my opinion, the current terrain style for the nether is challenging enough and also fun enough for me. The caves are also a awesome thing to explore, but it is kinda bland now-a-days.
