Now I'm curious: what other mods carry social stigmas in this forum?
I actually like having mods like BC TE, and extra utilities as long as they're "balanced" to the point of costing much more than their GT counterparts. I don't like multiple blocks that do the same thing except one does it better, faster, for less energy, and less material cost. Everything in a pack should have its place.
Also I've never actually used EnderIO personally but the reason I shy away from it is because from what I've seen it eliminates all routing and plumbing problems. I think those are some key elements in a design and just removing it from the equation isn't as satisfying.
