Im struggling hard with my WD in Act 3 as well. I can do Act1/2 in my sleep using my mf gear or gf gear, but switching to my best gear with resists, more dmg, hp, etc. I still die constantly. I have been using Blood Ritual for the past few days, and I like it when farming, but think Im going to switch back to Jungle Fortitude to see if it helps. I enjoy playing WD a lot, but they still need quite a bit of work. Supposedly they have some big changes in mind for the WD soon, but they havent said when they are going into the game. Right now it seems there is only a few very strong builds, if you have the right gear or high end items. All classes with the best gear should be killing much easier than others.
