I imagine at some point they probably did have some massive list... but what actually made it past that and into any sort of conceptualization stage? I'm sure not many more than currently exist.

I think the title of the article on Massively sounds more like what actually happened... where as videogaming247 screams out "Mythic cut over 90 classes from the game!" like they're trying to take advantage of other recent news and make a big story for themselves lol.
