The Barbarian's been put up now as well. I know it's out of date, but it's always fun to see how it's progressing.
So they've just been launched, so I can put it up here now; I've recently been working with the guys at Gamer-Source.com to set up a working version of the Diablo 3 Skill Trees
as they were at the time of BlizzCon last year; the Wizard and Witch Doctor are active and the Barbarian is on the way!
are starting to pick up again too, with the latest round of info released from Blizzard, so feel free to head on over and discuss it all
So just to point out, to save the questionsno, these aren't the official icons, everything here is custom-made based directly on the skill trees as they were in October last year, the only time so far that we've had complete knowledge of the classes' abilities as they stood at the time.
(and I have a newfound appreciation for the efforts of UI designers)
