After many work hours and setbacks I decided that Revision 3 of COM3D2 Modpack is stable and good enough for public release.
The thing with this sort of packs is that whenever I decide that it's ready, something interesting always pops up and I want to include that too and the cycle continues.
Well, here it is. I think it turned out pretty good and it should cover the basics. Let me know if you have any issues with it.
