I don't get your quibble about "cursive" not being an appropriate way to describe hieratic. Pretty much every Egyptologist I've heard speak on the matter uses the term "cursive," with Demotic often described as "even more cursive." And I've copied quite a bit of it and it is far faster to write with a nice fountain pen than even "cursive" hieroglyphs. It's not particularly difficult, either. Sure, it's more complex than an abjad or an alphabet, but I don't see what that has to do with anything. The complexity is far more in reading it than writing it. If we're going to talk about difficulty in both reading and writing, Demotic is worse. And let's not even get into Ptolemaic-period hieroglyphs...
