Minechem kinda imbalances GT. You can get Tungsten ingots very early and easily. Same with titanium, Aluminum, and Chrome. Also, right now its a little messed up. Like on tungsten will give you a nugget and two is suppose to give you an ingot (works that way with all metals) but for some of GT metals instead of an ingot you get an entire block instead. Basically Minechem removes the need for the industrial centrifuge. Oh you can all get free cells since you can get compressed air cells with two oxygen and then just empty the cell. I like minechem but it takes a lot of restraint to not use it to get around some of GT recipes.
