Indeed, as I main a hunter. I'm used to that kind of play style and you get shut down easily if your opponents take a second to think. I mean, I've even seen people jump off the map when they see or hear me. Sure, they die but I don't get the kill. Point is that there are ways to deal with sunbreaker. People just don't approach challenging supers correctly. If you hear a sunbreaker and have zero plans and run at him...well you're gonna have a bad time. If you realize that you can't beat him because of XYZ, then just run the -blam!- away. You can make it away from them if you're smart. And if you look at your surroundings and try to make them work for you, you will win. Use team mates as a resource. You run at two to three team mates with any player on your heels, chances are they're gonna back you up and shoot the damn thing. Or you can use low cielings and a sniper to be able to kill him after they come into view. Or use your vertical space to get the drop on him before he can see you.
