The only thing that gives it an edge is the health regen after killing someone. I almost kill a sunbreaker then My stupid teammate charges and gets killed and then all my shots were worthless because of my worthless teammate. Ive seen too many stupid people allowing the sunbreaker to get health. I don't wanna say sunbreaker is so much op but rather teammates are stupid when encountering a sunbreaker. I run sunbreaker without that perk. I feel more safe being my hunter going invisible with arc blade and striking at the right time than I do sunbreaking
