These are the builds that I've theory crafted, usually trying to centralize on a set piece and specific damage type. I haven't tried them all so there may be some minor tuning to do with the skills/gear. Use these guides as a good start/base-point.

Some builds are more gear specific then others. For the armor as a general rule of thumb, focus on capping your resistances. For weapons, focus on the damage type that your build does. Accessories give you a little wiggle room, can be more oriented for damage or resistance, which ever you're lacking.
