i wanted to caution anyone who got a level 60 creation from the cartel store or from being a sub when the new content came out.
i STRONGLY urge you, if you are creating a character of a class that you have not played through chapter 3, that... you go and do that BEFORE you go on to the new content.
you loose improvements to your heroic moment, buffs to your companions via story, and various other things... if you do not.
i moved on to the new content and really regretted having done that once it dawned on me what they had not given you with the leveled 60.
also, it gives your character a bunch of crew skills (at max skill level ie: 500) that are decided on what class you pick, eg: consular and sorc get synthweaving (armor that looks like jedi/sith should wear). there is a way to say "i want to do advanced customization" that i sort of glanced at, that i wish i had looked at closer that might have allowed you to change what crew skills you get.
just to be clear... once you click on that yes, "i want to move on to the new content" you loose the ability to talk to your original companions and their stories, play the original content class story, and impact your legacy related to those things... there is no undo... or going back later.
