Recursive subnetworks? I don't know what you mean by that, though at first glance it appears like a perfect way to fubar your ME network. I'd say it's something to avoid. Why would you think differently?What @Zarkov said pretty much. Excessive worldgen is a poor mechanic in general, imo. Then, do as he did and either create a recipe for the presses, or, if you're lazy like me, just pretend you're on a server and throw away some iron blocks (what it takes to duplicate them) and cheat them in. I actually like the channels, and once you wrap your head around recursive sub-networks (as well as p2p), they really aren't a burden.
