Thanks for the replies. To clarify, I am not wanting the Rebels as NPCs or PC's, I just want to understand the builds so I can do similar type of characters.
My other main question is, can you just do a Carer and a Universal Specialization vs. a Carer and a Carer Specialization?
E.g. could I do Kanan as Scout, Palawan Surviver; Hera as Smuggler, Ship Captain. I agree she is probably Smuggler, Pilot and Ship Captain (and maybe some sort rebel ace pilot later). But what I am trying to do is come up with similar but different type of characters. Example one starting character idea I have are the following:
Shri Ring[Worlder] - she goes by Sri Ran right now - A human ectogene from a distant Saturn Like world where they colonized moons. The people there grew their children in Ectogene tanks (so like a clone but more individual). They mature rapidly. Normally they were not force sensitive. But right at the beginning of the clone war, one was. She was discovered late, and trained with the younglings. Very soon after she was going to be a padawan and someone's padawan was going to be made a knight. But right at Order 66 right when she arrived. She ran away as the padawan and knight were gunned down and the clones didn't realize she was going to be a padawan. She has her lightsaber, and went into hiding. She is ashamed of her actions, and unsure of her survival for years. After a very dodgy time in the outer rim full of memories she doesn't really like to think about she is now on the planet where the campaign starts and finally found a group that she trusts. I would make her a Colonist:Padawan Survivor.
The other character I have in mind is a Gotal Shipcaptain. Smuggler: Ship Captain. He was on the planet of the campaign as part of the diaspora. His family has been gunned down by imperials when they took his farm. He now runs odd jobs. His only remaining family is part of the diaspora as well, but they are on another planet where the Gotal went far away (Lothal). That gives a connection down the line.
I have a few others like that, such as a Hired Gun / Ex Imperial. But none of the hired guns ones fit the concept for the character that are in the book (and after laying out like 100 bucks and not having played yet i don't want to get splat books yet).
Another is a Explorer/ExClone etc.
Thanks again, I like all the feedback and ideas.
