It can be easier to gain prowess charges unawakened than in an awakened one. Awakened, as long as you have the same amount of power bars, you remain in diamond form - great as a defender and a safeguard, however, you need to parry in diamond form to gain prowess and ramp her, whereas unawakened you're out of diamond form on the same energy level, so can earn prowess from being more aggressive. Awakened Emma will start in diamond, so if youre running suicides, she'll shrug them immediately, same with any node debuffs - also comes in handy when fighting something like biohazard. This months EQ she doesn't work as well. Its all down to personal preference really, my 6* naturally is awakened, I want to keep my 5* unawakened for as long as possible.
