In one way, I appreciate what the modpack developer has tried to do - leaving out some of the more popular mods in an effort to expose more people to the lesser-used mods... such as using Buildcraft pipes and engines instead of mods like Thermal Expansion and EnderIO.
However, as your "average" minecrafter, here's what happens... I place 1 bucket of oil into a Refinery to make 1 bucket of fuel... but when the process finished, I don't have one bucket of fuel, I have 960mb (millibuckets) of fuel, which is 40mb short of a full bucket. And THAT is the reason why, when given the choice, I would never choose Buildcraft pipes and engines over another mod's method... Where did my 40 mb of oil/fuel go? Was it stuck inside a pipe when I broke them? It's absolutely maddening when this kind of thing happens. Precision is important, and if a mod is going to cause that precision to fly out the window (for a reason I cannot figure out at the moment), I end up blaming that mod for it even tho it's probably my fault in the end for not understanding every little idiosyncracy of every mod. Off my soapbox now, and I'm off to take a long hike to grab one more bucket of oil from a geyser somewhere.
