I actually like the idea of having a heavy heal stance and a light heal stance the most. I hope they will go with CNJ for crossclass just because of cleric stance. But I think it's quite likely that the crossclasses will be CNJ (due to the useful spells AST would get, ESPECIALLY cleric for solo purpoes even) and ACN (Just fits well lorewise and spells would be useful too) but who knows. We might get some really fu**ed up shit.

I kinda wish to be able to use the cards at will though. I was thinking they might be the AST CD's. A heavy CD based healer with the standard heals on GCD.
