Half-Life reference, switching to RF and going back to old UU... This all feels like an early Aprils 1st joke...
In case its not, this is just depressing, dropping EU is forgetting IC identity itself, as Briareos81 said, many 1.9 mods are creating their own power systems, why not making a simple e-net for IC and evolving it? Of course it would be a lot of work at first, but just switching to RF is almost doing no work at all.
I hope the decision is reconsidered, or that its just a prank.
