Videos of the new heroes, shows the skills like on the website, but also has a small gameplay example of the skills combined. D-Va looks really cool cause you can boost the robot forward then ult and it explodes at the destination, great for clearing bastion and shit. Also interesting thing is her robot "health" is mostly armor, which means you can't heal it, but also mitigates small hits a lot due to how it works, which means Roadhog/Tracer/Reaper will do half damage to it(winston and zarya too if they use their lasers stuff).
