Thank you all for the very detailed responses.
Just one more thing:
Does anyone know whether or not your legacy transfers with you to a new server, regardless of whether or not that character is the original legacy creator?
From the FAQ: (http://www.swtor.com/community/showt...23#post6394323
Will my Legacy, Achievements, and Collections all transfer with my character?
Yes! All of your Legacy unlocks, Achievements earned, and triggered Collections will be waiting for you.
