For FTB Revelations I suggest to implement the Rockhounding Mod (Core, Chemistry, Rocks and Surface).
I like the tech behind it and how it works. With Rocks and Surface you have also nice additions for building purpose.
And for a suitable ore-processing-facility (x5) I suggest in addition Mekanism (Generator and Tools not needed, as e. g. RFTool's Dimensions AddOn is not present, which means no high energy consumers).
I also wonder, why WR-CBE, Advanced Solar Panels and PortalGun aren't in this pack.
For the magic side I added AbyssalCraft and EssentialCraft 4 Unofficial. Also I added ThaumicAdditions, ThaumicBases and Thaumic Periphery for more stuff with Thaumcraft 6.
BloodMagic received Anumus and BloodArsenal for more stuff and also for testing even if they are beta or alpha mods.
Finally I added the following mods:
Actyally Computers, Immersive Cables, Immersive Tech, Questionably Immersive, Thaumic Computers, zettaindustries (Big Battery, RF Meter), JustEnoughPetroleum, tc6aspects4jei and jeivillagers.
Would be nice if a few of them will be implemented into the pack
