Sunbreaker's super is OP because every single perk the subclass has revolved around it. They get no passive abilities nor combat abilities outside of their super. The class itself revolves around the super itself where as other classes do not. Yes it takes two golden gun shots, however you can fire them in rapid succession, kill the sunbreaker, dodge the hammer and bam. You have 1-2 more shots and deprived the Titan of his super which takes a whole minute longer than yours to recharge. Nova Bomb kills it. Tether takes it away. Striker Kills it. Machine Guns Melt it. Two quick sniper shots kill it. It's by no means invincible and it is better than other mobile supers strictly due to the fact the super is pretty much all the class has too it's name. Before anyone criticizes me because I main a Titan, I main Striker and Defender, not sunbreaker.
