A DA warlock with no fury can't teleport away nor leap away, can't use his shield nor knock back/interrupt, no auras, no sleep... All these abilities cost fury, and all you need to do to stop it is quickly killing that pet (and imps) and preventing that warlock from casting too much, which is fairly easy if you are attacking with a group.
Also, dark regen + hearthstone combo, with a mortal strike effect up, is currently slightly less then 50% health, will be even less in 5.3.
As for the damage reduction, it's all fairly equal to warriors in defensive stance, death knights in blood presence, etc... In terms of magic damage reduction, they are below disc priests which have about 35% reduction.
So technically, DA warlocks work but once they get low on fury with their fury generation crippled they are useless.
