Fury's synergies are very weak! Pierce is much more important - get 100% with Razortail. It's useful to max one (or two synergies for ChS's sake), but don't max all three. Especially for hc, put some points in passives - about 50% D/A/E after items is nice (if you're going for a cowazon, Evade is most important), and valk level 17 after items is very useful.
