Not to be outdone by TalentChic, the folks at 3D Armory also sent us their lists of what the most popular builds are in the game after patch 3.1, and since everybody seems to be build-hungry lately (and why not -- we each get two!), here they all are.
Warrior: Fury 18/53/0.
Paladin: 0/0/0, which means you need to log in, Paladins! Also 51/5/15 for Holy.
Hunter: 0/0/0 wins here, too, but Survival (6/14/51) comes in next.
Rogue: Combat 15/51/5.
Priest: 14/57/0 for Holy.
Death Knight: 17/0/54 Unholy.
Shaman: Elemental 57/14/0.
Mage: 0/53/18 Fire.
Warlock: 0/41/30 Destruction.
Druid: 14/0/57 Restoration, which surprised me.
Keep in mind that these are from only a small sample of the game, so they're not the most popular specs in the game, just the most popular among those surveyed by the 3D Armory. And unfortunately, unlike TalentChic, it doesn't look like there's any way to see where the points are going, just the distribution of points among the trees (though that reminds us that Blizzard probably has some amazing point-by-point stats on how popular talents are).
