I'm terrified of Darth Ahis.
But with regards to the concept itself it lacks conflict and is very generic. Since they've already accomplished the task of being the "loyal, tough, fearless, smart and unafraid of death," of the sith empire's specialized military personnel there's little room for dynamic development. That would suggest you should create a character who is prepared to play a role not roleplay.
But to that end, you're appealing to a very big group of people in the MMO RP world with that expectation so good luck man.
