I know boniggy made a profile for alliance that levesl inscription with the use of blackfallow ink. Since they put in the ink trader it's become far less time consuming. I went from 1 to 400 in about an hour. I'm still trying to sell off glyphs of course, but that's only because i didn't do it as I went.Find someone with Inscription 525. Buy Cataclysm Herbs and ask him to mill them and create you blackfallow ink.
Once you've got round about 1500 inks you can trade them for the needed inks and skill 1-525 in 1,5 hour...
In my opinion Inscription is by far the easiest profession to level.
