Been enjoying my Barbarian immensly since patch, i uploaded a vid few days ago of the "Obelix"-spec. It's a little more tuned currently but haven't made a new video. Don't miss the old WW-spec at all, and best of all - no rubberbanding/deaths which was connected to that spec.
try doing Torment 5 or 6.. Crazy hard for Barb... doable, but not as easy as before. Challenging tho. I'm comfortable doing T4 right now solo, but once lvl 70 gears pops up and new skills opens.. it would be interesting where the barb again.. but of course, gotta try the crusader first
