Just curious. What is the difference between Tekkit and Technic?
Technic is the main compilation, whereas Tekkit is the revision with only Bukkit-ready mods.
The Jungle biome will make the huge rubber trees from technic pack even more useless.
There will be a use for them. Same with marble, basalt, tungsten, and gems, Eloraam included all the resources before adding a use so that you wouldn't have to keep ditching your maps every time the mod updates.
