Not only have I noticed 85%+ of top arena teams are horde (racial surprise), but DKs went from over represented to not at all.
Could this be they've been nerfed so badly that they arent viable? I mean, just comparing to an enhance shaman -
Strangulate - 2 min CD, 5 sec
Hex - 45 sec CD, 8 sec (can be instant as enhance)
Mind freeze - 10 sec cd, melee range
Wind Shear - 6 sec CD, ranged
Icebound Fortitude - 2 min CD, 20% reduced dmg, costs runepower, prevents stun
Shamanistic Rage - 1 min CD, 30% reduced dmg, usable while stunned
Damage, bascially the same, if not more for shammy (scourge strike does paltry damage)
Now this is just ONE comparison, but really, why are the numbers so OFF with no compensation to DKs? I know they WERE op, but now, they arent represented at all, and if so, barely.
edit - Forgot to mention shamans have spirit wolves to match ghoul stun, with a shorter cool down, BUFFS from totems, and near immunity to snares.
