See, this is the kind of thing I've wanted to see! People finding inventive ways to use classes over jobs in a viable way! Although I think the only other truly viable one would be Archer over Bard...

It's a shame that some people are so resistant to trying to do things any way but the known standard. So called "Elites" who've memorized all the standard strats and standard job cross-class skills who freak out upon seeing attempts to push the envelope and experiment a little. Letting the game fall into repetitive complacency isn't good for it!
