If Ghost got buffed slightly I don't think Kensei would have to be nerfed, as the main offender of what makes these classes good actually lies in Duelist and not Kensei or Ghost.

Yop I agree to this aswell. I also feel that Ghost still has a few areas in which Kensei just can´t compete aswell, but usually my pick goes for Kensei because of the utility of actually FP recovery and the few extra bits of Crit you gain from Wazabane. Basic attack builds just feel Rewarding and are fun to play imo.
So overall I agree with what Spo said, Ghost probably just needs a few tiny buffs here and there and it should be alright.
