This is confusing. There's almost no changes in this pack except Quarry, Computers, and few others. If you're under the impression the pack encourages you to use ALL the mods, that's incorrect. Some mods are untouched (according to NEI). The description led me to believe I'd be encouraged, somehow, to complete other mods. Hunger overhaul is there but none of the foods have been nerfed, that I could tell. Can eat bread forever if you want. One barley farm and 33% of the Dark Trilogy is negated.
It's possible some more changes are coming, but there's no list of what's been altered. GregTech, at least, had documentation. The change log only lists updates/fixes to the mods in the pack, not changes to the recipes in the pack. It's possible I've gotten a bunch of this wrong and I got a partial download which didn't have all the changes, but from my end you may as well build the pack yourself, that way you can alter it with the mods you want to try.
I was kind of hoping I'd be forced to choose Thermal Expansion, Ender IO, Extra Utilities, Tinkers' Construct, or IC2 for Basic Ore Processing and then once I'd reached a certain point I would have the materials for the next (higher) Ore Processing tier, but unfortunately (as far as I can tell) they're all untouched and you can choose any one of the these for early game and completely ignore all the others. Making it a pack with mods you'll never use. (ie. a normal FTB pack)
