You must be watching different lets players and reading different forums than I... people are having a hard time adjusting to copper being on a different level than diamond, so people aren't so flush with copper as they are with Iron. I have far far far more Iron than I do copper.
Oh, I've been watching people playing the DNS techpack in that instance; copper is much more abundant. I recently played a Direwolf20 game where i had a ton of copper starting out too. Since I wasn't doing IC2, I had no other use.
I'm sort of fascinated by these modpacks where they remove the (stupid) EU system and replace it with universal electricity's more realistic modeling. Given that RP2 is basically dead these days, I'm sort of at a loss on what to do w.r.t. a less absurd electricity model. There is just so little you can do with blutricity.
