Dancer damage is low, partly because with the Flourish change, we lost extra procs, which weren't compensated. And, yes, the new skills are locked behind long CDs, which kind of sucks.
Also, Tilana makes no sense. Seems like it should just be higher potency and not refresh Standard Step. What possible situation is there when we'd need and extra refresh on Standard Step? It's a one minute buff with a 30 second recast that we do on cool down. Tilana is the strangest, most pointless skill ever.
So, at the very least, Dancer needs potency buffs and Tilana needs a change to either just do more damage, or have an actually useful bonus on it. Maybe increase Esprit or something.
