If you define mining as waste of time I wonder why you play this game
So you have the decision between going to nether or making a gregtech blast furnace, not so bad imo. Besides it is weird that everyone assumes they _need_ a mining drill for whatever reason Oo
Don't ever use the argument that people who don't like gregtech just want "cheap and easy", because there is a hell of a lot more to FTB than just IC2 and some of those things represent a hell of a lot more challenge than just grinding materials and feeding machines. Savvy?
Well the thing is quantum armor = easymode, thus it should be hard to obtain~ General rule: more powerful item => harder to obtain
Yeah it isn't _that_ hard yet but that doesn't really point against GregTech
Challenge in FTB? Hmm dunno it appears challenge is whatever you make it. You don't need to do anything besides building a dirt hut to be able to say "I'm done"~ You want a mining drill? Well then you go get steel.
You're too lazy to make steel? then you automate it, or not~ etc
So which challenges do you make for yourself, those that you are talking about? Sure theres more to do than just making quantum, but its a part of the challenges one can make for themselves.
Besides, GregTech makes the end interesting (note: in newer versions) <3 something which all other mods seem to have failed so far
And GregTech does more than just changing a couple recipes, it also adds nice and fun new tools to play with
