I get why people think that Sunbreakers are overpowered. The super is nice, but it's the first decent offensive super we have had. Personally I think nothin should be nerfed because we are still pretty vulnerable due to the slow attack speed. I have killed Sunbreakers and been killed mid Hammer of Sol more times than I can count by two people concentrating Fire on me or a couple well place shotgun shells from behind. It is very close to the overpoweredness of blade dancers, who have an oversheild, can teleport and are super agile. I have put 3-4 shotgun blasts into blade dancers mid super and never put a dent into their oversheild. That subclass has never been nerfed... I would be willing to compromise though. I would trade a shorter super or less of a shield for a more powerful melee i.e. A one hit kill charge like other classes (looking at you warlocks) and a more powerful sticky grenade that actually finishes off the person it sticks to. I think that would be a more than fair balancing considering the melee is sub par in crucible and the sticky grenades are virtually useless unless stuck to an already wounded opponent.
