IC is dead (atleast it seems so).
Mods Like TE,EIO and most notably Big Reactors came out of the ground and made IC useless.
I like IC more than for example TE, because of its Style and its balance.
The reasons why IC is unused:
-The Voltage System (one of the key features of IC) has been removed.
-Some machines in other mods do the same as IC machines, just better.
-Some machines/items in other mods are far OP, thats why no one uses IC reactors anymore.
