Raid Issues: Out of Combat Resurrection

If you've done much end-game raiding, then you've heard about this tactic – out of combat ressing involves having a player stay back from a fight and remain out of combat so they can resurrect players killed in the fighting.  And this week Blizzard confirmed that players were never intended to do this – an interesting move, considering that their own tips page once included the tactic – and modified combat mechanics to make it impossible.

The implemented fix causes everyone in a dungeon to be flagged in combat whenever anyone attacks a boss, which has had interesting side effects
for rogues vanishing and hunters feigning death, though Blizzard says this is as intended. 
How has the fix effected you, or has it?
