My response as to whether I keep my much the same or not will depend on this: synch rates change, right? Over time I can increase the level that I start at, and there are things I can do in battle to try and temporarily increase my sync. At least that is how it sounds to me. If that is the case then I'll keep black star the way she is and fumble through it for a while. If not then I'll change it to more of a support roll mech.
