I have legitimately gotten everything built here is my bugs/opinions on the mod.
1. Can't make a mass fabricator with the current version legitimately!!! NEI does not work with whatever you made the new recipe and it is not the default one from IC2
2. Solar arrays require ridiculous requirements took about 20 hours to find everything required to make the main things just to make one regular solar array which you need 512 of to have 1 HV...obviously way to ridiculous I believe the main issue here is the industrial centrifuge this also makes it impossible to have a 100% automatic factory for solar arrays which I can do with IC2 it is of course a MASSIVE factory already but gregtech makes it impossible On top of that you are making a blast furnace just to be able to make it as well. You basically need everything in the game already just to make an industrial centrifuge and you are doing it with a geothermal generator because it's all you got until you get to this point...
3. NEI get's completely over written with gregtech and losses a TON of recipes from the other mods, it looks like gregtech is actually trying to completely make his own way to IC2 instead of it just being an "addon"
There is a lot of perfection/tweaking that needs to be done so this works with everything else. The worst part is, got all the way to the point of making a mass fabricator legitimately after all this time and there is no recipe and the default one does not exist what's the new recipe? is it even possible? it's not in the recipe list provided on the forum...
