Also, let's not forget MFR and the laser drills, which I think require upwards of 5,000 RF/t to operate at peak efficiency. While I agree that it does contribute quite a bit to the ever-increasing amounts of RF needed to perform certain tasks, it does get kinda nuts, at least in my opinion, when a single, relatively small reactor can make around 20k RF/t, and that's with passive cooling.Part of the RF 'arms race' is because of AE. It's just that powerful, and all the bits take energy. Lots of it, if you're using the quantum rings. But more than that, once you start auto-crafting or setting it up so it's auto-crafting, all the machines it's working with take power as well. And because most of us don't want to sit and wait on an autocraft, we accelerate the machines. What took 20RF/t, now takes 100. And chances are you've got multiples of it. Eventually dynamo's can't keep up, even upgraded. So you move x8, and x64 generators, then on to reactors. And then turbines. And then realize you still need more power. It's not necessarily a bad thing, but too many people skip the entry level and jump straight to the top for no reason other than because it's there.
Its also another part of why I don't do BR til after I dip into ReactorCraft, its part of a self-imposed challenge. Without it, I don't have a massive source of power that requires a fairly simple setup to achieve; I have to go outside the norm to fuel my various contraptions. For example, my current SSP world is mostly being run by a small bank of IE thermoelectric generators, a bank of 9 regular furnace generators using aeternalis fuel (since it lasts FOREVER), and an IE diesel generator, which I've config'd back to default. I haven't broken into auto-crafting and some of the more complicated bits of AE2 partially for that reason, and also because I'm trying to find other ways to achieve what I want in that regard, which is why I'm dipping into Logistics Pipes and learning to better use RotaryCraft's auto-crafting units. That way, I cut down on the RF used to power AE auto-crafting, and get a few more tricks up my sleeve. Given a Big Reactor, all those little extra things I've been learning would be obviated because I'd have tonnes of excess power lying about. Now, I've gotta play smart til I break into fission, or maybe thorium now that its working.
