I simply can't make it work, I'm squishy an endurance hog and god I'm just plain squishy. I don't see any builds for this is it not popular at all?! The gaps are enormous if it's not the endurance it's the survivability I can't seem to find a healthy mix any input would be greatly appreciated he is my first fifty and I really don't want to scrap him.
