I'm not feeling low on dps as dancer. It feels about right as well as the buffing. i tend to partner my bf's monk and i just end up swimming in Esprit. Heck a few runs i'm second or third dps with the monk in first though this is pug parties so take that with salt.

Either way the dancer isn't under performing depending on who you partner with. It does feel like partnering with either Monk, ninja or bard are your best bets if you want high esprit generation for saber dance. With esprit being generated on spellskills and weaponskills high skill/spell speed partners are your best bet if you want to prioritize saberdance. That said there is no problem if you rather pad the blackmage or samurai I just prefer generating that Esprit myself.
