I'm assuming you meant 'sunsingers' (never heard of sunbreaker titans with radiance lol). But yeah- I ran across a squad of Sunsingers when Mayhem was first released and it was the most annoying -blam!-ing time I have ever had in PvP. They had solar grenades in every -blam!-ing corridor that is was almost impossible to get out of our spawn (yet alone even see the douches to snipe them out of their camping spots lol). Hat's off to them though- they exploited PvP much like the 4 titan bubble/2 hunter GG combos did. lol

I don't have sunbreakers but I still have the best time doing it
