Having same question here. I am in the process of making Gregtech 6 server and i want to add more mods that will work alongside gt6. But most mods are breaking balance or too independent of GT and that`s just not server theme. Currently i have only GT6 (finally got rid of Railcraft after Greg adding water barrels) and some mods like chisel, carpenters blocks. Even in chisel you have to disable granite generation or it will lead to lvl 4 hammers too early in the game.
So, is it just too early to make such servers or i need to just agree that not everything should be in sync with greg?
