Rey
Rey is one of the easiest heroes to use in the game and is also quite powerful too. She has the most health out of all of the light side heroes and pretty good speed. Her abilities mainly act as enablers to allows her to get kills with her lightsaber. She has good stamina as well and is quite easy to pick up. Her mind trick ability inverts all enemies within a distance in front of her controls and reduces their turn speed by a lot. They can still attack and use their abilities though, so don't run in front of them as they can easily attack you. This is best on heroes as a lot of them rely on movement and also when you get behind a group of enemies, as once you do it, they won't be able to turn around. When you mind trick a saber wielder or someone with a high damage gun like a scatter gun, get behind them and kill them as a saber wielder will block you from the front and a scatter gun will deal a lot of damage. Enemies can dodge and roll while mind trick, so expect some enemies to dodge you and also force users will use their jump, so target blaster wielders as they are a little easier to kill. Her middle ability allows you to see enemies through walls, so you know where they are. It also takes you of their radar and gives you unlimited stamina while its on, s use it for easy flanks and to escape enemies. This works really well with her dash ability as you can see when someone is about o come around the corner, so you can dash them immediately. Her last ability is her dash which is really good in all scenarios. When fighting a hero, you can dash into them which stun locks them, then immediately attack them for some easy damage. This combo can 1-shit weak health heroes like Boba and Iden. For regular soldiers, if they are in numbers run through them for some easy kills. This works well for escaping as well, so use it there as well.
