You kind of failed to dismiss much, I agree with most of thatBravo! Now THIS is how you start a flamewar!
So I'll summarily dismiss it.
The issue people have with Gregtech is a modpack maker issue. It is an overriding mod which was hard to ignore in 1.4.7 and grew even moreso in subsequent versions. Due to this and its power to dominate a pack, it honestly should never have been included in a mainstream pack targeted at a general audience. Period.
That said, Ultimate was the torch bearer for "all the things" packs. I personally see a shift away from those types of packs. With the community knowledge gained from configs settings and the ease of modpack creation, there truly is no need to be dependent on launchers to provide packs for you. Just do it yourself. "Private" packs are all the rage and rightly so. Smaller, better curated packs suit specific playstyles better than 200 or more mods thrown together.
Either way, OP, just make your pack yourself. If you're really dedicated, submit it for public distribution via ftb or ATLauncher.
Modders shouldn't be taking on the roles of pack makers. Back in the day, the lines were a bit blurred, and GT crossed them. Nowadays, if someone wants to mess around with something like 1 wood = 4 planks, they typically do it with minetweaker, and they're typically assembling a pack that does so for a reason.
