This mod is stupidly difficult, which is a shame, because it could be fixed so easily. This mod is cool and all, and some of its stuff, especially the ore duplication, is unmatched, but you seriously need to go and make this natively support RF. It is already the standard power system for tech mods, and is rapidly becoming the only viable system for mods to use. Not just Thermal Expansion anymore; Mekanism abandoned universal electricity in favor of RF, the Forestry update is making it RF native, BuildCraft is consdering switching to RF, and IC2 just adopted RF as its primary power system. RF is better in just about every way, its so much easier to understand, it is used by just about everything, and its so simple and clean that its so much easier for computers to run. The days of 10 mods and 10 power systems are over, and you need to wake up and adapt or this mod will ultimately die off, and that would be a shame. The clock is ticking, and the choice is yours. Tick tock.
Think for a second here, what you are asking Reika do to here is to stop making his mod... Rotary Craft's energy system IS like two thirds of what Rotary Craft is about, the fancy machines are merely rewards for those who have mastered the energy mechanic.
You want Reika to essentially GUT his mod to turn it in to a sad Mechanism clone with bedrock tools... Also one data point that clearly reveals you don't know what you are talking about; You mention RoC's ore duplication is unmatched, but you then mention Mekanism which has ore quintupling and easier quintupling at that. That being said the extractor does handle more types of ore but it's hardly unmatched.
If in some parallel universe @
Reika was to consider converting solely to RF my suggestion would be that he just shelf the whole project and not bother as we don't really need another Mekanism/ Thermal Expansion clone. Even if hypothetically RoC did suck and was a lag monster, you still have no right to tell him to neuter his project, you really don't, you don't pay him in any real way. Sure state an opinion, maybe even suggest something but don't give prescriptions to fix a problem that isn't there like it's something he needs to do or else.
There's two types of tech mod player I think:
The first being those who like the mods for their technical aspect specificly, who enjoy thinking and liked stepping down currents and routing stuff to the right place. The benefit of their build being a pleasant secondary effect and acts as more of a confirmation of their planning and work being successful.
These are the players I think RoC and ReC caters for.
Then there's the other type who treat tech mods as a means to an end, those who only use a mod becasue it gives them more resources or for an easy jetpack. The convenience is the sole reason they use the mod with most complexity being unwelcome as it's merely a barrier keeping them from their real prize.
Essentially they don't like tech mods at all despite what they claim, they just like magic boxes. Which would be fine if they where just honest about it, I mean come on everyone likes a bit of magic box now and then.
