So, I'm looking at WDs and Barbs and these are my thoughts:
have played this as my first S6 char and did the gr75 and gem lvl conquests before playing another class
pro: I know what I'm doing and the class is super strong
con: I'd just repeat what I did some weeks ago
have loved the whirling game since the glorious days of ICEBLINK and not played it since S4
pro: I'd like to play a fresh class
con: Whirlwind is considered bad, don't know if I like the other builds and how they fare vs the WD (can I reach my goals with it?)
I know, I could have the stash tab 20 hours into the season. Won't happen. No energy drinks, no dedicated level group and potentially other stuff to worry about. That being said, I don't consider myself horribly inefficient.
The only other class I haven't played in S6 (see signature btw for what I toyed around with) is the DH, though I have plans to just play her in NS with the UE gear I have from S4.
