Worth it, but if you really want other type and have a plan to do some RS soon than wait until then. Personally I really really wouldn't mind raising a breaker.
I am raising up my breaker. TBF, its Vesti. **** the typing, she's awesome as hell. Also got a lord: Not selling her, since I might eventually need 2 squads for something, and two vestis are better than 1. And 1 vesti is better than none. And oracle vesti is better than none. So Vesti > oracle vesti > no vesti.
