I can kill a Bladedancer with a shotgun and a melee. I can kill a titan in his bubble with the correct timing. I can kill a gunslinger in his super, if I can flank him. Novabomb's and Fist of Panic's kill potential, are balanced by the fact that their usage is a one time thing, on one single geographical point. If there weren't 5 people at B, you won't get 5 kills with them. However, the Sunbreaker can pop his super, run across half of the map with his 60% damage reduction without dying, and wipe a whole fireteam. Not in melee range? Just use the pseudo golden gun. In melee range ? Just use the pseudo arcblade. The Sunbreaker has 2 form of counterplay: Waste your own super. Or run away. No other ability has this unbalance, because ranged supers either have no damage reduction (GG), or can only be used on one single point of the map (Novabomb). For someone who played as much crucible as you did, you sound pretty clueless to be honest.
