I made some PvE DPS class and spec statistics based on Raidbots. I selected the last 30 days and 10m normal using link:
http://raidbots.com/dpsbot/Spec_Scor...14/30/default/
The amount of samples was 551,165 and this is how they are divided to different classes:
Hunter ... 15.17%
Warlock .. 14.65%
Mage ..... 14.20%
Shaman ... 10.10%
Rogue ..... 9.69%
Priest .... 9.45%
DK ........ 7.39%
Druid ..... 6.94%
Warrior ... 6.15%
Paladin ... 3.67%
Monk ...... 2.60%
No big surprises here. Hunter is the most played DPS class. Over 15% means that basically almost every 10m team has a hunter (or the teams containing hunters produce way more WoL logs than the teams without hunters). And Monk is the least played DPS class, probably because it is so new.
Then if we look at the DPS specs the situation is this:
Hunter Survival ... 10.98%
Priest Shadow ...... 9.45%
Warlock Destruction. 8.50%
Rogue Assassination. 8,46%
Shaman Elemental ... 7.39%
Mage Fire .......... 6.91%
Mage Frost ......... 6.57%
DK Frost ........... 6.04%
Druid Balance ...... 5.47%
Warrior Fury ....... 4.82%
Warlock Affliction . 4.54%
Hunter Beast Mastery 3.84%
Paladin Retribution. 3.67%
Shaman Enhancement . 2.71%
Monk Windwalker .... 2.60%
Warlock Demonology . 1.61%
Druid Feral Cat .... 1.47%
DK Unholy .......... 1.35%
Warrior Arms ....... 1.32%
Rogue Combat ....... 1.20%
Mage Arcane ........ 0.72%
Hunter Marksmanship. 0.35%
Rogue Subtlety ..... 0.03%
Hunter is strong here too. If you don't know what spec you should select go Survival Hunter. More than every 10th DPS character is specced as Survival. Poor Subtlety, out of 10,000 DPS characters only 3 selected Sub spec (and regret that).
Then we can also check how it goes inside a class:
Priest Shadow ..... 100% of DPS Priests
Paladin Retribution 100% of DPS Paladins
Monk Windwalker ... 100% of DPS Monks
Hunter Survival .... 72.39% of Hunters
Hunter Beast Mastery 25.31%
Hunter Marksmanship . 2.30%
Warlock Destruction. 58.03% of Warlocks
Warlock Affliction . 30.96%
Warlock Demonology . 11.01%
Mage Fire .......... 48.67% of Mages
Mage Frost ......... 46.25%
Mage Arcane ......... 5.08%
Shaman Elemental ... 73.15% of DPS Shamans
Shaman Enhancement . 26.85%
Rogue Assassination. 87.28% of Rogues
Rogue Combat ....... 12.37%
Rogue Subtlety ...... 0.36%
DK Frost ........... 81.78% of DPS DK's
DK Unholy .......... 18.22%
Druid Balance ...... 78.80% of DPS Druids
Druid Feral Cat .... 21.20%
Warrior Fury ....... 78.45% of DPS Warriors
Warrior Arms ....... 21.55%
Ass-ass Rogue dominates here, almost 90% of the class. Marksmanship, Arcane and Subtlety are not in good shape.
