Before upgrading from one release to another I usually do this:
* Run "yum list extras" to find any packages that didn't come out
of my chosen set of repos. These are likely to throw up
dependencies that can't be resolved from my repos once on the
new release. I remove them prior to upgrade and reinstall
afterwards.
* Run "yum update yum". Newer versions of yum are typically more
capable and efficient than older ones and could save some
time/grief.
Doing this, I've always succeeded (with minimal fuss) upgrading from
release to release using yum.

I think this is because of any combination of the following reasons:
* other OSes don't check dependencies
* other OSes come with a tiny set of software compared to FC
* on other OSes dependencies are checked by app installers at
install time, later removal or changing of required stuff goes
unnoticed until the app mysteriously crashes
* on FC, package maintainers make mistakes in specifying
dependencies, or go over-zealous with dependencies (specify
something that's not actually required)
Me? I prefer to have dependencies checked and maintained whenever
something gets installed or updated. I find the time required to resolve
dependencies pales in comparison with the time required to download the
stuff.
