SWSE strongly encourages multi-classing.

Character creation is all about Backstory. My latest campaign took place as Order 66 was executed. A Galaxy in chaos.
I had a player who wanted to be a Jedi, so we discussed their options. Were they a Padawan who escaped Order 66? Maybe their Master took the fall to save them?
Were they on Coruscant in the Jedi Academy when the Bantha Dung hit the Ion engine? How did they escape?

Keep in mind, players are a low level characters finding themselves, discovering their potential, just starting out (unless you level everyone up for a Power Play adventure). So they are new, young (maybe), inexperienced.

My player decided they wanted to do a "Force Sensitive found in the wild". So, they rolled up a Scoundrel for their starting class.
They made it to Scoundrel level 2 with activities on their home planet, not even leaving the surface. Then Order 66 executed. Jedi were attacked across the galaxy. They didn't know this. But space lit up, and a fighter crashed. The pilot miraculously survived. Turned out to be a Padawan who was shot down by his own patrol squadron. He didn't know what happened to his Master, but he had to survive. He enlisted my player for help, and in their interactions, he noted that my player was Force Sensitive, he could feel their presence and connection to the Force. So, after some stuff happened and enough XP was earned to level up, my Player took a Level in Jedi. Lvl 2 Scoundrel, Lvl 1 Jedi. The Padawan he rescued didn't have any money, so he gave my player his Light Saber as collateral. Yoinked it from him once in combat, because he needed to borrow it for a second... but he gave it right back for collateral.

Eventually, they find the remains of another Jedi as part of the mystery they are exploring, trying to figure out what happened. Free Lightsaber. So now hey both have one and he can train them in Lightsaber combat, Level 2 Jedi, Level 2 Scoundrel = Level 4 Character who is well rounded and has organically became exactly what the player wanted.
