I'll admit, at first, I was one of those that cried "nerf" on the introduction of the Sunbreaker. But after playing PvP and learning to counter them, the only problem I've ever had with Sunbreakers is the Cauterize perk (I have a Titan, had one since before TTK and loved being a Striker, Cauterize is very powerful) but I've learned to counter. Smart players learn to counter. Hope the impending nerf doesn't kill Sunbreakers for good, they are a good challenge.
