just wanted to pop in and let you know that we will be making a change concerning the loyalty to the sith warrior achievement. Jaesa will no longer contribute to this achievement. Her individual light/dark side achievements will still be available, but you do not need to max out either alignments to receive the loyalty to the sith warrior achievement. We made this decision because from a technical stand point, jaesa is considered two separate companions and we realize that it isnít fair to make players play one version of jaesa over another in order to receive an achievement -- when no other class is required to do so. Completionists can still do so to receive the individual jaesa achievements, though.
I do not have an exact time for this change, but i will update you once i have more information.
