Dragonfel, the packagers are fairly useful. So are the wrath lamps. Also, factorization craft packets allow for a computer controlled sortron-powered automated crafting facility
Packagers can be pretty useful in certain situations, like xycraft block storage, but your video showcases how well red power can use factorization, not the other way around.
I mentioned in my previous post that I think of factorization as the "wrath lamp and barrel mod", and I agree both of these things are fantastic and my base wouldn't be nearly as well sorted or lit up without them. My only complaint is that the power generation and processing machines are convoluted and archaic compared to others in this mod pack, and for what they can do I do don't feel it necessary to bother making them. Hopefully neptunepink adds more functionality to them and maybe more power options.
