You have Gellius AND Jessica, what kind of Heavy woes you could ever have then?! Raise them, pronto.
Duelist-side, you have quite a lineup to chose from. Clissa would be my personal choice to raise first as valkyries are good at doth dueling and ramping up, and, well, she's black, what other reason you ever need?) Or even better, Sherry, cuz dat AW passive...

As far as Awakenings go, as you seems to rely on fair share of golds-, Sherry would be a solid first choice. Then, usual Spica and Iris are always good units to have. I would also personally recommend Shuuka, for her great utility as ramp and anti-zerg and even support.
