I personally think EE is overpowered only if you have the time to make it to the OP stuff. ( :Uranium Ingot: in my scale)
But hey, that's just me. I want your opinions.
Feel free to use this grading scale thing:
:Iridium: = Pretty balanced
:Industrial Diamond: = Balanced, but a little OP
:Uranium Ingot: = Half and half, but leaning towards balanced
:Energy Crystal: = Really in the middle
:Uranium: = Half and half, but leaning towards OP
:Mining Laser: = Really OP, but a little balanced
:Nuke TNT: = EE, go to hell (Way too OP)
= What's EE?
