While I'm familiar with and more or less fond of RoC farming machines, I think this is the first I've heard of someone saying they "beat" MFR. By most definitions (efficiency, ease of use, power) I frequently hear the opinion that MFR is still far better, especially if you're including the whole farming scope (including tree-farming)
For myself, I'm inflicting some sort of horrible self-punishment and trying IC2/GT farming these days.
....it hurts when you're used to either RoC or MFR. :\[DOUBLEPOST=1407353599][/DOUBLEPOST]
The later versions of RoC handle this far better. If you're up to date, you should consider saving your world and trying a bedrock axe on it, see what happens (mostly because I'm curious
)
