Well, for one, I'm moving the data from 8.1.6 to 9.2. Wouldn't a full import overwrite the data in the system and ctxsys tables (and some others)?

Also, wouldn't I get a boatload of errors as foreign keys fail to find their parent records, grant statements fail to find the referenced objects, views fail to find their underlying tables, etc.

I can see a full import working if it's done just the right order, but I don't see how to guarantee it.

In any case, I did try a full import at first, but everytime I tried it the import process would hang. Others here suggested importing just the application data, so that's the path that I'm on now. If there's an easy way to just import the whole thing at once I'd be more than happy to use it.
