They basically turned her Flash Grenade ability into a very powerful Barrage ability from the Heavy with her throwing 3 Thermal Detonators. It seems a lot more aggressive than how Leia has been portrayed so far in this game and in the last one since she's never had anything to deal with a large amount of enemies grouped in an area. I'm stoked with the change since it gives her a lot more potential in the large game modes like Galactic Assault. Plus, her shield now passively heals friendly units. Not too sure how that will change the dynamics around her shield, but it's a cool change regardless.
