I'm actually looking forward to a dancer class i the future. Always wanted to play one in FFXI but I didn't get to far on my own so I just watched someone else with it and it was awesome X) Also we have so many references we can use now, dancer class would be an easy hit with the playerbase.

For one we have Shantae from Shantae and the Pirates Curse



Mint from Threads of Fate (she isn't a daner but she uses chakrams and casts magic)



Yuna from Final Fantasy X2 (technically a songstress but uses dances too like Darkness Dance)


Of course they to give us more moves than that.
I think we really need this, it'd be a different ball game for dps, kinda like astrologen.
