I've been playing on and off since shortly after launch. I have long since completed all 8 of the class stories and unlocked light and dark 5. I understand that my characters who have finished chapter 3 of the class story will be able to pick their second combat style immediately and all new characters that I create after 7.0 launches can pick theirs immediately. I also have characters that I have created over the years to do different play throughs, like finally playing a dark side jedi, that have not yet finished chapter 3. When will those characters be able to pick their second combat style?

After completing chapter 3 of the main story
