Razortail or thundergods vigor? Which one should i use for a pure lightningzon? I'm leaning towards thundergods, because of the lightning absorb, better stat bonuses, 3 to lightning fury and that it's called "thundergods" which looks great on a lighningzon. But I'll need to invest alot of points into pierce which I don't want to. If I don't use razortail, how many hard points will i need to spend in pierce to get a reasonable pierce chance?
