I agree with this.The IC2 eco-system still has the most server-friendly infinite-loop power generation in the form of HV Solar Arrays. I use that to power my AE system, tools, Mass Fabricator, and Overclocked IC2 machines integrated into my AE system for on-demand recipes.
But, I do indeed use 36HP-based MJ power for everything else and could indeed do without EU entirely as the original poster has stated.
But, I would also not want to see the IC2 ecosystem be taken out of DW20 or Unleashed. It's a good set of mods for what they do.
I also wouldn't want to lose my precious reactors... even if they do explode every now and then.
