The class looks really cool. The "dance" mechanic is quite novel for MMOs (even if it is just Simon Says), and I'm quite intrigued as to how it will work in actual group content.
Speaking of FFXIV, I'm really excited about Shadowbringers, especially the class overhauls. However, I don't really want to play FFXIV right now, and level classes with the old mechanics. Ironic.
