Just swapped out my Legs which was 530 (I JUST BOUGHT IT AS WELL!!!) for a 520 pair and noticed everything flowed better and my Blasting Zone aligned back to how it was, meaning aligned with Gnashing Fang. Can't believe it. I wasted my upgrade on something I don't need. Will have to wait and swap out other SkS pieces now. Anyways, I will meld Crit and Dhit I think.
