Since there's been a lot of discussion about how the end should be reset of modified to add more ores and such, i've been looking for mods that specifically make the end bigger, but i don't know how it would effect the generation of gregtech ores. http://www.minecraftforum.net/topic/1416293-146-endless-end/ It's a cool mod that makes the end stop generating like a platform in space and more of a massive landmass. It does add a few tools and blocks to the game that you might want to disable if you chose to add it. The only bad thing is that it's currently only modloader, so it modifies some base classes, but someone is working on porting it to forge.
So instead of a tiny floating island, you have a whole world ? OMG, it looks like there gonna be a lot of bases
