My biggest problem with the new enet stuff is that it swings a horrible nerf bat a large-scale power generation.
Let's look at some of the new MOX designs, some of the CRCS outputs, and my old Tower of Power build.
Tower of Power had multiple nuclear reactors which were outputting something like 7k+ eu/t. Unfortunately, you can't do that anymore.
The maximum you can transmit is the glass fibre cable's 2048 EU/t. However, transformers don't act like they used to anymore.
Transmitters will only output a maximum of the lower voltage. That's it. So when trying to 'step down' to Extreme Voltage, everything else is truncated. In other words, you might as well not have bothered making it.
However, if you've got enough energy going into it, you can have multiple outputs from the same transformer, which can help you realize this truncated value.
However, now we are running into a tree-traversing algorithm here, with regards to space required to safely transmit all this power to the end-user.
You have one input and five potential output slots, although you are only going to realize four output slots. Now then, is all that power supposed to be going down to the same area? Congratulations, you now not only have four times the amount of cabling you have to run, but you've also got to color the entire length of the bastard, just to keep them from burning out. Then, when you have to step down again, it gets even more rediculous.
So, say, I have a power generating facility generating 8192 EU/t (there's MOX generators that can hit this, even if they are condensator or CRCS designs). First off, I have to have the transformer directly attached to the generator, because there isn't any cable that can handle this.
Then I need FOUR LINES of Glass Fibre Cable (at a diamond per block of length!) to transmit this power. Then, when it is further split down, I need SIXTEEN gold lines, which is simply an unmanageable snake of wires large enough to take up almost half of a 9 x 9's space.
All of that hassle just to USE THE POWER I AM PRODUCING.
In other words, IC2-EX is not only demanding you to produce that kind of power for things like the new UUM system, it's also harshly punishing you for even ATTEMPTING to do it.
Just... no.
