Ok, wow, there is SOOOO much gold here, I don't even know where to start.
Assistant editors are trained button-pushers who don't really understand technology!? LMFAO!!!! Dude, this alone has revealed the level at which you work. Anyone who has worked in the business in Hollywood will tell you that typically AE's know the software FAR better than editors, and spend most of their time cleaning up after them and correcting their mistakes. I know this, because I've WORKED as an AE in Hollywood.
People weren't complaining about FCPX because it got rid of LiveType... It's because it got rid of very important professional features like OMF, and XML, to name a few... Most pros don't do their own titling... we leave that to professional Motion Graphics guys, and just use a basic text generator or still made in photoshop as a placeholder until we get the real deal from then MoGraph guys, which the AEs then cut in and we approve, or don't do anything with at all because by that point the cut has been locked and we've moved on to another project. Guess what - we don't color correct either. That's for Colorists to do. Sound? Yup. We have pros do sound too. This isn't to say that an Editor can't be good at these things and cannot do these things... but specialists are typically better, and that's the way it works in Hollywood. The fact that I've had to TELL you all this tells ME that you really have no idea what you're talking about.
Indie work? Student and amateur films? Sure, I'm sure it's just fine - but this is not really pro level stuff, is it? FCPX may be a great editing tool, but it's just not ready for the big-leagues. It's entirely irrelevant how pleasant it is to cut with if the AE can't send my work to the Sound guy, or the Colorist, or even put it to tape without some sort of ridiculous workaround. Apple eliminated CRUCIAL professional level features from FCPX, and that's precisely why NOBODY in the business is using it.
