I main dnc on my alt and I find everything you complain about, enjoyable. I like that dancer is busy, and tbh its really not that much busier than other classes. There is plenty of time to weave in fan dances, the dance procs are easy since you get them all at once and don't have to wait to see which ones next, making each step easier to execute, the high dmg phases is the most enjoyable part of dnc rotations imo.

There is so much time between cool downs that weaving with dancer is a cinch. Sure you have to pay attn but since when is that a bad thing. I can only see this job being difficult if you want to just tap the same 3 buttons in the same order constantly and not have to worry about procs or weaving.

As far as combat goes I think dnc has the most thoughtful design behind it. They really took a lot into consideration so things lined up nicely.

And since you need to be level 60 just to unlock the job, its clearly not meant for newcomers....
