I guess I would like to know the point of using the GregTech nerfs in a modpack with so many alternatives: do people who like the GT nerfs actually plan on building all those expensive IC machines, or do they just plan on using TE for everything instead? If you like the solar panel nerf, do you actually plan to build solar panels at all, or do you just plan on switching to infinite lava? If you like the macerator nerf, are you actually going to build a macerator with that recipe, or are you just going to use one of the other dozen machines that double ores? If the only point of the recipe nerf is to make it expensive enough that everyone will use an alternative machine instead, then it seems silly to even include the IC machine at all.
Why is this an either/or situation, particularly when the two systems are on separate power grids? Look, I love TE for a number of reasons and it is one of my favorite mods. And while it doubles ore it is not nearly as fast as an overclocked rotary macerator / induction furnace combo. There comes a point where either project scale eclipses your current setup, or you desire something from another mod. A pulverizer is not going to put me in a grav suit. So why limit yourself to the use of one or the other?
Even having switched ore processing to maceration (about when I stared having a full MFSU and could afford to overclock) I still use my TE workshop extensively (liquid redstone, conduits, cells, accumulators, xposers, etc.) My original SSP map went from TE steam / forestry biogas, to crucible / magma engine + geotherms, and presently has 2 full sized steam boilers and a couple of advanced solars contributing to each side of the power grid (and a tank full of unused biofuel). I'm spinning Deuterium and Tritium to prep for a pair of Fusion reactors while I mine the universe for iridium with 10MJ/t quarries that dock with redstone cells. This whole experience without the beauty of RP or TC. My sorting OCD fixed by barrels and routers. My mad genetic scientist fix through bees which provide infinite materials. A robot that shears my sheep and could probably repair the national debt if I could code lua worth a damn. And the list of potentially "OP" things that GT doesn't touch goes on. What it does touch is IC progression, both for its own balance and the "too easy" nature of the toys that directly impact the avatar, which is a distinction from standard world blocks. Something like a quantum suit should be an effort (in order to provide greater satisfaction in the achievement), not something you should necessarily be able to make with 60 chickens in a tank and a solar panel.
At any rate, the entire progression thus far has not felt as out-of-whack as people are making it out to be (in a beta pack with a ton of moving parts, nonetheless). I wanted a drill, I went to the Nether and got brick. I wanted a macerator, I ponied up some diamonds - which were honestly easier to supply than the initial gold for TE when the map was new. This is kind of child's play compared to where GT is heading anyhow, so if you don't enjoy it now because you feel it is either difficult or tedious, that probably won't change. I do agree with the complaint about the ore dictionary, but deal with it because I'm progressing both trees and have a full workshop of gadgets.
What bugs a lot of folks about this debate is the fact that the mod in question is one-click disable - never mind configurable - and doesn't warrant this much drama. If the launcher had a way to generalize difficulty (Easy, Normal, Hard, Oof) and tweaked the mod configs accordingly, a ton of these complaints would melt away, which says more about end user complacency than anything. It would be equally as ridiculous if those who liked the mod came here to complain that it wasn't on by default with the same frequency were the situation reversed .. which they wouldn't. They would just turn it on and play Minecraft. I realize this is probably a logical argument to disable it, but it somehow doesn't jive with the "everything on by default, remove what you wish" nature of what will become the Ultimate Pack at some point.
