I would add something to what I said previously :
I do not recommend new player to go with Jedi. The main issue with this faction is that they are rapidly underpowered compared to other factions. They become great at end game so you should farm them as a minor thing after you got your first goals.
At the moment, Rebels are great for many things (Raids, Galactic War, Arena and story mode). So I would recommend to go with them.
Also, it's not about character directly but this is related : save you crystals for energy refresh (both Cantina and Story mode). Cantina is your top priority, you want to get gears as fast as you can to develop your chars. Do not spend more that 100 crystals on refresh, you can wait for the day after.
And finally, there's an important thing to know : 3 times a day, there's a free energy gift -> At 12.00 PM, you get 45 energy for both Cantina and Story mode, then 18.00PM and 21.00PM there's another one 45 energy refresh for Story mode. This is a thing to know because if you don't pick them within 2 hours, they vanish.
I personally use them every time for Hardnode giving shards in Story mode or when you need to farm purple gear.
