I've Gone and Made a Mess (10 player)

A reference to Moroes - A Karazhan boss who as anyone who played during TBC knows loved to Garrote random raid members, putting a dot which damage piled up when more people had it if you didn't have a few paladins for Blessing/Hand of Protection.

When he kills a raid member he says 'Oh, I've gone and made a mess!'

--edit: Seems that now they've changed the achi. Rather than being 'Kill boss X before they Garrote X people in the raid' its now 'Defeat the Deathbringer before Mark of the Fallen Champion is cast three times in 10-player mode.' - which isn't really a Moroes reference without the garrote, just the phrase now.

Getting the achievement

Saurfang casts Mark of the Fallen Champion every time he reaches 100 Blood Power. So to get this achi, you just need to kill him before he does that 3 times.
This is done by doing the following:

• 
  
• Keeping your ranged raid members all spread out at least 12 yards apart. Saurfang will be casting Blood Nova on one random ranged member, and it will splash to anyone nearby. Anyone who takes damage from this will give him 1 blood power.
• 
  
• Not letting the Blood Beasts he summons (2 on 10 man, 5 on 25 man) every 30 seconds or so melee anyone. The blood beasts need to be kited/stunned and not land a melee hit on anyone. For each swing they land, they give Saurfang 1 blood power. Recommend using hunter slowing traps, earthbind totems, typhoon etc.
• 
  
• The Rune of Blood will be put on the current tank every 30 seconds or so. When Saurfang melees the tank with this debuff, the tank takes more damage and heals Saurfang. Some places report the healing being negated if you just swap your offtank to a DPS spec, but for this achievement you also need to consider that Saurfang will be dealing 2 sources of damage when he swings a tank with this debuff - his white damage plus the damage proc off the rune, and so he'll be getting 2 blood power per swing instead of one. You can simply have 2 tanks rotate to negate this.
• 
  

Very unusual achievement, I would be amazed if anyone did not get it on their first Saurfang kill (my raid certainly did) - it would make more sense if the achievement was "Defeat the Deathbringer after allowing Mark of the Fallen Champion to be cast three times" - because realistically, for a group learning the fight, if you get three people marked, you're going to wipe. Letting him mark three people and still finishing him off would be an achievement.

Hmm, unannounced visitors, Preparations must be made...
