@OP: How about you take a small step back and do a small bit of a rethink. I agree that there would be some great things to integrate into forge, but why do it?
Ores. It would be awesome to have the support and gen from forge, BUT think of this......you do that and you're left with 1 type of copper. Just 1 to look at. Not 5 different textured ores, but just 1. Wouldn't it get a bit bland after a while? While we can get some spectacular views above ground, still need some underground! With most mods using the oredict, all it comes down to is just the views associated with the mods. Besides, what would all the texture artists do if forge handles the ores? It's not a matter of it being a bad idea, but you'll see why most will disagree
Tools. I love TiCo, and I love how there is becoming more support with it. Unfortunately, the player base is pretty diverse. Some find it daunting to figure out tinkers. Alas, if it gets integrated into forge, tinkers will go out of business. Again, you'll find why most will disagree with it.
Optimizations. Excellent idea, but as mentioned before me, every system acts differently.
Duel-weilded weapons would be cool thing, but there's mods that do that already. Again, more modders out of business :/
Nei, hell....I don't live without it. But, there's a lot of clutter it adds to the screen. Not all players like that, and again, putting it into forge makes more modders obsolete.
See, when it all comes down to it, your left with a few basic facts. First, all you'll be doing is turning forge into a mod pack itself. Second, there will be a lot of folks not able to revolutionize in their own ways. Lastly, not everything fits for every player. So it's not a case of communism, it's a case of freedom! It's a case of variety! It's a case of a keeping forge doing what it does best! We all love the idea's, even if most won't admit it, but it's just a lot of creativity that will end up lost
Qucik edit: Electricity, since I seen it mentioned. That one would be great, but it comes down to difficulty. RF is pretty easy. EU is a step up, and RotaryCraft is pretty banging on it. Some like it easy, some like it difficult. Making it all universal would disrupt the balance on existing mods which are balanced in their own way.
