I've really dug wolfie druid. 1-120 with no respecs. T1 Grim Fang --> T2 Enyo Long Sword --> T4 Void Long Sword took me past Hell Duriel just now.
If your not lazy like me and uptier your items along the way, he should be solid. P.Flash is a great killer when Harbinger is dangerous to use, and makes for some nice summons.
Alas, i must respec.... at some point. I'm sure i'll struggle with some ubers, but he kills normal areas in Hell pretty quick, so i should start racking up some set/uniques eventually. Anyways, just wanted to share my experience with my first character this version; and also my first wolfie.
