Well it's missing Refresh for one, and obviously the skill that's not shown on this the flourished fan dance, and there's probably a gauge dump single target ability and I assume Chocobo Jig(Peloton), unless they cut all these role skills.
The base combo is slightly interesting though because when I thought about it, it's actually somewhat less boring than RDM. RDM is just Jolt > Verwhatever, if proc, replace Jolt by the proc but always hit the long cast after, and Impact when it's up and you don't get a proc. But in this, while you only have 4 actual buttons, the fact they can proc or not proc independently so you can sometimes get non proc non proc, or proc non proc, or proc proc, or non proc proc. So it varies a bunch, especially if the flourished version don't interupt combo, since they themselves aren't part of combos.
Also the DNC movement skill is so cool. 3 charges of a dash, on a class that doesn't even have cast time, shit's gonna be so easy to dodge stuff with. I kinda hope they'd give it some skill that's like Rescue, so you can dash to a safe spot and pull your dance partner to you without having them to deal with mechanics. Carry them garbo DPS by buffing them and moving them around.
Anyway now I'm sure of what I'm playing, just need to find something to do for a month while I wait zzz.
