If your shard is infested with zEP teams and your jedi are up to the task, then it could be worth it. I run zBastila / zGMY / zEzra / GK / zHoda and non-Traya zEP leads are full auto battles. With Traya under zEP I make sure she dies after Thrawn. Traya leads with Trooper can be a challenge depending on how well modded the opposition is, but DN in place of GK handles that easily enough (unless there's a seven star super fast Nest, which is still possible, but not as easy).
I've run zEP teams and the RNG associated with mirrors in maddening. zBastila trades that discomfort for having a harder time with Traya leads.
