I plan on keeping my world for a long time and building the machinery is not the fun part for me- the machines are tools to help me along the path of building. Because of that, I choose to go with easy mode for machinery.
I tend to play under the idea that every mod worth being in a pack should be focused on enhancing the players gameplay experience; not simply making things more tedious to be 'harder' so that you can afford the time and effort to make a machine that builds other machines from the same mod.
That's why i detest Greg tech and the way IC2 has gone.
The most fun I get from technology centric mods is trying to eke out an extra 2-3% efficiency fuel/energy usage, an extra 10% on production, a lower TCO (total cost of Ownership) for similar processes and reduction of footprint for any given setup.
Being a blanket 1'up device does not fit that bill.
Mod makers need to stop focusing so much on 7 step crafting, arbitrarily adding whatever is the rarest commodity and 'standing out by plagiarism' at any one time and start focusing on getting people WANTING to use their mod.
One of the biggest problems is not how power is handled in ftb, it's the fact that short of quarrying and maybe a forcefield system, large scale intrinsic power production has very little usage or point. it's a bit like not automating a base and playing minecraft simply to keep investing 90% of your gaming into simply maintaining it running 24/7 so that you can enjoy exploration and intricate design in your almost non-existent downtime.
That's right the way Minecraft is being modded makes it more and more like a JOB, than a game.
