Any list available??
No, different heroes perform differently (and very drastically differently) depending on whether you pilot or auto, whether the bounty target is stationary or mobile, whether the bounty target is at high plat, or gold, and a whole lot of other factors.
Typically, to simply do the most damage, I just choose elemental damage boosting heroes. I’m sure it’s not the most efficient way to play. I would be most agreeable to hearing other player’s strategies!
