I for one prefer this system. A few transformer upgrades in each machine and you quickly raise max EU/t far above EU/t cost. I supply 512 EU/t to my machine shop, the 512 line is split into 2, so I send 256 to each side of the room. Every machine has 2 transformer upgrades and 3 or 4 overclockers. None of them explode, none of them receive too little energy. Once I put my max 6 overclockers in every machine, I will probably need to upgrade to 3 transformers per machine and boost the input to 2048. Simple.
I admit its more complicated than the old system, but I think that's a good thing.
