If you don't want only dps and you want to prove a little bit support role, these traits could be a good choice:
Fast loader: your mez will be without induction
Healer: +10% (or +15%? I am not sure) heal on healing skills (also share the power), -50% induction time, some cost reduction
Light of the hope: Beacon of the hope has only 20s cd, less moral costs and -0.5s induction time. Until lvl 77 (when you get water-lore) is this one a little bit better than Healer.
Improved Flanking: target of air-lore will be healed everytime, when you heal yourself with flank heal.
As pet maybe bear, he has decent dps and can take aggro on himself when needed. Eagle could be later also a good one: interrupts, fear, self rezz, many flanks.
With rk as dd I think he will have almost allways aggro, so some heal traits could be good. But don't forget about your cc skills and debuff skills. They prevent you from dmg.
