Nah.. there is a definite progression in FTB, and it's actually quite good. It's just that the fully automated options for mass mining (eg, Steve's carts) take quite a lot more configuration and setup than a simple quarry.
It's just that EE3 with the Minium stone makes it dead easy to whip out tesseracts, which make it even easier to power a quarry and feed the items back into your inventory.
Agreed. EE3 also makes it too easy to acquire blaze rods, which makes the alternative to Tesseracts - color-coded Ender Storage Ender Chests and Ender Tanks - also too cheap. A BC quarry by itself is perfectly balanced. What is not balanced is how easy it is to support the (remote) energy and item infrastructure that effectively trivializes them.
An early-to-mid-game quarry that requires local power and local item processing would be more balanced, IMHO, and a more sensical progression, i.e.:
- diggy diggy hole
- diggy diggy hole better/faster
- 1st quarry with limited power and crude item processing
- 2nd and subsequent quarry with more power and better item processing
- ...
- Nth quarry with Tesseracts/EnderStorage powered by (near) infinite energy and (near) infinite item processing
If that occurred, I think you'd see a more linear progression. As it is, once the 1st quarry is built with 4 Tesseracts to support it. 62x62, let it run overnight, and a (too) huge a leap forwards has been made.
*note Liquid/Item Tesseracts into Magmatic/Steam/etc.,. Engines also trivializes quarry power generation
