Could be your UI. I'm so use to WeakAuras from WoW that I struggled with not having strong visual indicators with this proc heavy job. Make sure you can easily glance at your buffs/Dualcast, Veraero/fire, and your balance meter. Once I found a comfy spot for everything it was just a matter of learning the rhythm of dualcasting. Took awhile but the job went from feeling clunky and a bit overwhelming to quite fluid.
