My favorite heroes for HvV. This list is mostly going to be heroes that I came up against in HvV and decided to try themselves and ended up loving them .
Light side
1. Han Solo: I never really liked blaster heroes until I started using Han. His blaster is lethal and his bomb and his charge buys him a lot of time.
2. Rey: She was the first hero that I used when I got the game and I liked her a lot. Her mind trick is good to buy you a little bit of time and her dash is pretty decent too. Not best lightsaber hero, but I like her.
3. Leia: Back from the dead. I played her like once or twice before and there was nothing really about her that was strong. After the update she's a beast. Her thermal detonators are great and I love that her shield regenerates health now. Quickly rose the charts
Dark side:
1. Palpatine: Again another hero that I used a lot when I got the game and I just found him fun to use. I wish his stamina wouldn't drain as fast as it does, but otherwise I think he's great.
2. Kylo Ren: I like all of his abilities and I think they fit his character very well.
3. Phasma: I mostly started using her because I absolutely hated going up against a good Phasma. Gave her a run out and I saw why people used her. Her blaster has good range, her survivalist greatly helps her health and her staff does a good job to help fend off lightsaber heroes. Her droid controls areas insanely well.
I think both the light and dark side heroes need another lightsaber character soon. I think you need to get Ahsoka and Ventress in this game to change it up a little. Would love to see Mace Windu in this as well. After that I'm not sure who else to add.
