IC2 died a long time ago. Until it's flipped on it's head, hogtied, and thrown into a pack of hungry wolves after being stripped naked and this is all taking place in Russia in Winter, I fear that IC2 will never really be noteworthy again.
That being said, the "Alpha Knight" that I am(as far as Minecraft goes, anyway), I remember when IC1 was first released. It was simply ground breaking. Even the Ore Doubling was in almost everyone's eyes a breath of fresh air. Now, here we are. IC1 was back in Alpha. IC2 was released roughly coinciding with the release of Minecraft Forge IIRC. It hasn't changed much since then. Crops were added, Nuclear Power changed now and then, occasionally rehashes of IC1 items came back into the fold, but it hasn't changed much since those Alpha days.
But then again, almost every mod owes favor to IC1/2 in the end. Many things were first done in a good way by IC1/2. Not everything was done well. But many mods have roots that tie it to those early days when they only "real" mods out there were IC2, BC(2?), and Redpower. After all, weren't those mods the ones that sparked Minecraft Forge? BC was for sure, and RP almost made it worth getting for RP alone, but IC2 was still very important. But this was so long ago. RP and RP2 died long before Elloram released RP2.
In the end, I only have IC2 core for one reason; UUM. With GT, I have a bit more reason. These new changes don't sit very well with me, namely the countless small bits you need to craft the occasional machine or tool.
I usually didn't even bother with IC2 and GT when I last played. But still, I loved them to bits. GT because it was a very needed bunch of items for IC2, and IC2 because so many mods used it(and UUM). Now, I may just wait until the storm passes on this issue. I am uncertain where I stand on the matter.
Well, no, I know where I stand, but that's with Magic Mods. Tech is cool and all, but I prefer Magic. Even Thaumcraft was more up my alley then IC was. All of the TC versions were to me.
And most of them have merely been Tech mods pretending to be Magic mods.(TC4? Yeah, it seems like the real deal for Magic to me)
But, I wouldn't be happy to see it vanish. I may look into RotaryCraft, but last I checked it was all kinds of weird and complicated looking. I mean, I know I(and everyone else, really) were spoiled by KingLemming and how Intuitive TE was(and it seems he has spoiled me even more so with his Redstone Flux system and his Tools that use it, rather, one of his Tools that use it), so, maybe the fact that it looked more complicated then even a basic TE/Mek processing line was didn't help.
In closing, I am no longer able to use TiC with a clear conscious. As stupid as this may sound, it was always more powerful then it needed to be, and Dartcraft, my preffered mod for the whole "pick your enchantment for this item" system got a horrible rap, occasionally even being said to be as bad as EE2(IIRC). I at least take faith in the fact that Dartcraft, which has been nerf'd hard, and truthfully, kinda needed it, it still is more balanced then TiC.(and seems it always will be since TiC tools don't break, can be given weird, somewhat conflicting powers, such as stonebound and anything that is an alternate to tool damage, making them stupidly powerful, and if armor is added to TiC, then a slew of new issues will arise on the matter of "what is the best suit of armor and why?")
