My berserker is about to be 86 and I'm considering investing into him. Can someone show me their preferred skill build? Currently I have everything maxed except Gore Cross (0), Burst Fury (1), Blood Ruin (0), Bloody Twister (1), and Diehard (dump, currently level 3). I don't know if Diehard is worth prioritizing for the strength at later levels and if I'm maxing something that shouldn't be. I use a mist katana currently and is it worth it to use katana mastery even though the class is mostly fixed? Is it mostly a waste of points? Any help is appreciated.
