A late night hotfix has been pushed to live servers which allows DKs and Warriors to now counter Incorporeal! Not only that, Death Knights are probably one of the best classes to have on Incorporeal weeks.
Death Knight Incorporeal
Death Knights can now use Control Undead on one Incorporeal every set as this ability has no cooldown. Not only does it neutralize the Incorporeal but it actually casts on your enemies as well reducing the damage and healing they do by 5% a per stack*.
