A barb complaining about a class that counters barb. Interesting.
SB is fine, and not because I currently play one. The damage is nothing special compared to other DD classes apart from perigean tide/call lightning. One had a high cooldown and one requires someone to debuff you FIVE times in a row without you purifying it before it does decent damage.
Meanwhile it takes 5k+ from instacast ea's with 97 def levels and full rpd gear on. The only thing that should be changed on the class is more pdef. There are WAY too many existing counters for the class to warrant a nerf.
