Oh, agreed, if one uses gregtech the teching is clearly slower. It feels much more fluid now though, and feels like it makes sense more. Now the natural tech solution is kinda like:
hand-tools > heat-driven (mainly) mechanics > basic electrics > advanced electrics.
I much prefer that to old tekkit's
hand-tools > electrics > electrical mechanics.
It feels more fluid and less weird. I'd say more natural, but nothing about minecraft is natural so that's kinda moot.
I kinda like that though. I always find my first (and sometimes second) setups to be temporary regardless, as I generally move my base at least once or twice depending on how far I've gotten in the game.
But since engines are so easy to move - just get a pickaxe or crescent hammer, no risk of getting destroyed etc - it's quite easy to make a permanent setup and later upgrade it anyway in the beginning. Just put the machines next to each other and put the engines behind - then when you upgrade, just remove the engines and replace them with conduits.
