Thank you. You made my point right there. Without BC, Forestry and Railcraft, there would *be* no Force Engine. Where I come from, clearly overshadowing your mod parent is considered rude behavior.
Without BC, there's no MJ, so your whole point after that is invalid. But I'll humor you
As for the Force Engine, 1 bucket of Force lasts an *incredibly* long time and a better setup than water is a single cow with a single Rancher, i.e. replace water pump / aqueous accumulator with a Rancher + Cow in a pen and all it done. 12 MJ/t easy as pie. It gets even more insane with Icy Bees. As for Force, just put Force trees in a MultiFarm and call it done.
Your second point illustrates how a combination of Thermal Expansion, MFR, and Forestry bees and farms are required to maximize DC. I don't see how multiple mods interacting is causing DC to over-shadow them. If nothing you've proven that your over-shadow point is illogical. This is a shining example of inter-mod interaction and support. They play well together!
There's also a reason a Combustion engine will blow up if it overheats - power. 6 MJ/t *used* to be considered a lot of power for a single engine that requires just fuel and water inputs. Sure, Industrial Steam Engines output 8 MJ/t, but they require very longtail boilers to ultimately be more efficient.
So no engine is allowed to be better than a Combustion Engine? We should still be worried about power gen from 1.2.5? Spamming engines is still not creative, its just that, spam.
Then, *whammo*, Force Engines come along and make those engines obsolete. To me, that's less creative, not more. Bigger numbers != creativity.
Combustion engines are old hat. Many other MJ producers are better and more widely used. Many don't use them because of the explosion issue. Magmatic engines are still en vogue. Boilers are generic MJ producers that are automated very simplistically. They're boring but there's not a real alternative in FTB packs for mass MJ production. If anything you're illustrating how people desire better MJ generation methods than SPAM all the engines.
As for my game and my creativity, I'm worried that DC will do to BC, Forestry and RC as what has happened to SC2. SC2 has become a vanity mod since it is clearly underpowered/overpriced WRT to all the comparable mods. That's a shame, 'cause it's a great mod with some very cool mechanics.
So DC replaced bees, tanks, rails, butterflies, oil world gen, item transport, logic gate systems, offered multiple tree types, etc? That's not true, and its ridiculous. Your point is as logical as how much DC replaces all the armor and weapons that Buildcraft provided. Wait, BC doesn't add that. LOL
