To be honest the only thing we can spec for in the subclass is our super (by giving us additional hammers, adjusting flight paths) but none of the other perks in our setup really work for PvP (Sunspots are garbage in general) so obviously we aren't going to cripple our super by using perks that don't give us more bang for our hammer. The DR is ridiculous though, and needs to be toned down enough that GG can one shot it. I would urge you to play as a Sunbreaker for a while, and gain some perspective other than the "Wrong side of the Hammer" point of view.
