Hello, this is my build of Ray, and for me is the best and I hope this can be useful.
My focus is to let Raynor with a good HP and stun enemies with Bullseye , get faster to escape or kill the enemy with Revolution Overdrive , and use the raiders to pursue the enemy.
I do not like Hyperion , because it depends on the situation, if you are in a group with Tyrande (using Starfall ) , with Nova (using Precision Strike ) will be very good use Hyperion because it has many chances to end the opposing team. But this varies from player to player .
