Our group has been playing EotE nearly weekly since release and on the whole I think everybody has really liked it. I have had a few elements that have bothered me, and a lot of them have to do with skill breakdown.
For the most part I appreciate the simplification of skills. In WeG you had to have a huge list of repair skills to cover everything. It was a big pain. i tend to think FFG has overcompensated a bit going the other way, and that the all encompassing "Mechanics" just seems to broad to me. This one skill covers fixing everything from a toaster to a hyperdrive. I realize our characters our heroes are greater then the average Joe, but for one person to learn all of the things encompassed by "mechanics" would be literally impossible. As written, it is the ability to build, modify, and/or fix literally anything.
While I don't want to break it down to far, it seems logical to me to have a mechanical skill for Ships, Speeders, Weapons, Droids, and perhaps a generic "Mechanics" to cover the rest. I'm just thinking out loud, so my list could certainly be tweaked.
--While I'm at it I also tend to think there should be a thrown weapon skill.
