It would be nice to have a portal/end gateway at spawn or someplace that sends you to a new spawn in new chunks. Or would that go against the grain? I might start playing on Sur1 or 2 after the update but I want to be in new terrain.
I've noted some spots on Amp where I saw lava fall for the first time so that I can go back to them after the update to get fresh terrain nearby. So fortunately it shouldn't be too hard to find it on Amp. On the Amplified world a lot of the negative coords are still unexplored, even fairly close to spawn, because the /rtp on Amp ONLY sends you to positive X and Z coords.
