In beta barbarian felt awsome - wizard didnt felt as powerfull. Wizard fel abit plain, so thats the opposite of what i expected, i think teleport will make her alot more fun though. Mobillity(leaps, teleport, roll etc) mechanics added a ton of flavor to their classes.
Wd was really akward, even though he saw the highest numbers, 180+ yellows with 5 souls, he still seemed to kill slower than for example demon hunter and wizard .
Purely based on beta i would never chose wd as first main - but then i checked out his later skills in a preview and calculator, and tbh the variety and power of some of the later runes and skills made my jaw drop - the woodoo tree for example. I think Wd will be the strongest inferno class when his dots, cc and minions really get time to shine on the harder mobs.
