not to be a knife in your master plan here but i dont really like this MAINLY because of crap EU rates you propose currently are far lower than the current ones other than that it looks fine
(1 lava cell=20000EU currently)
(1 lava cell + 1 water cell + refined iron=3000EU your version)
im not liken it
I told more than once before, that all numbers or values can be changed for more balance, lol
If IC2 team want, they can set even 1 000 000 000 EU for "1 lava cell + 1 water cell + refined iron"
