You've pretty much boiled down the complaints people have had with IC2 for the past year or so. I like IC2, and I enjoy the crafting changes they've added, as it makes things a bit more interesting (or complicated) to set up. That said, there's really no compelling reason to add IC2 to a pack other than you enjoy tinkering with it. It's a bit of a dinosaur, and that's fine, but if you try and compare it with more 'modern' mods, it becomes clear that it really hasn't changed since 1.2.5, and it shows.IC2 is seriously flawed if it can only be used in a modpack alongside its direct competition (as it were). i.e. if, for example, IC2 needs buildcraft pipes, who (in their right mind) would use an IC2 miner when there is the BC quarry available?
Off that topic, I'm surprised no one mentioned Ender IO for item transport.
