As a player if all classes, I have to say that cauterize is just such bs.. Mind you I've spent the past 2 day as a titan trying to grind to 40. Every kill with a class skill gives near-full health. Thats grenades, super, and punching.. add in sunspots and armor and its stupid tanky. I feel like I am way too OP compared to my Nightstalker (main) and Stormcaller.. On the good note: I love all the classes and honestly think if buffed slightly, the other two classes could compete with Sunbreaker without an issue
