BEFORE PROCEEDING:

From this point forward, remaining characters and ships are not required for specific events. (I'm not counting TB here, because the next few characters do still contribute to specific TB combat missions.) From here forward, the "15 hard nodes per day" recommendation can be relaxed or intensified to your own inclinations. At this stage, there's a LOT of gear to catch up on, so focusing on a single character, and the rest of your energy on gear, isn't a bad plan. Go at whatever pace seems right to you, or check in with your guild leadership to see if they recommend a certain level of investment in any of your incomplete characters, versus investment into gear farming.

That said, next up is Count Dooku, who is found on Light Side 1-C AND Dark Side 1-C.
