You say doing this would get rid of a problem, but this problem isn't Greg's. I doubt he gets payed for every user playing a particular FTB modpack built around the balance of his mod. This isn't Greg's problem. A fun pack was put together based around Greg's mod, you can play it or not. Personally, I've never played FTB. I enjoy putting my own pack together, adding and removing mods and resetting my world all the time. It doesn't benefit Greg in any way to appeal to more people. In fact, quite the opposite, he'd have an influx of dumbfucks constantly hounding him to make it easier, or yelling at him for "Going too far" if more people played the mod.
Hmm, I suppose that is the case, but even so, this pack is designed with gregs interests in mind, and if people decide to use this pack knowing full well that it has greg hardmode configs, and they complain that it is too hard, then there is nothing they can do about it, since its not designed with them in mind. I just think having more mods will appeal to the people that enjoy the Gregtech hardmode experience, but are not using the pack for the sole reason that it does not have enough mods. And the people that aren't using it anyway, and are against greg, have another argument as to why you should not use this pack.
