Interesting mechanic, basically all of Saurfangs abilities grant him Blood Points (BP) when they do damage to enemies.
The key is to manage the amount of points he is getting because when he gets to 100 (you can see this by checking his energy bar) we will cast a Mark on a random raider. The victim of this mark will take large amounts of damage consistently for the rest of the fight and if a Mark victim dies Saurfang gets 5% of his health back. It can not be cleansed and persists through death so Soul Stone / Battle Rez etc are out
- Tank Boss at the bottom of the stairs so tank is facing ranged dps
- Melee stack and go nuts on boss, be careful of AoE though as boss will spawn adds that need to be kited and killed other wise mass amounts of BP to Saurfang
- Ranged must spread out and be 12 yards from each other, this is definately a fight where stacking melee is going to help.
- Healers should be evenly spread as to cover mark victims (shields on marks = win)
- Setup a slow zone where hunters lay traps and shammans put earth binding totems down as required.
- Have your pally healer up the back with your boomkin. RF the adds and then when they get near Boomkin Typhoons then back to the slow area
- Adds should be focussed down (left right side focusing on a set mark)
- At 30% Saurfang does a soft enrage so big heals and you’ll be fine.
Ideally you will get to 30% with about 3-4 marks if adds are being managed and people are not stacking on each other.
Once he soft-enrages even if he heals (from marks) to be greater than 30% he will continue to enrage so if you are having issues keeping marked victims up you have a another option.
Basically the concept is to dps the boss to about 35% and let the clothies with marks die. Lets assume we got unlucky and ended up with 2 clothies and a melee dps with marks.
Let a clothy die and he will be up to 40% again but we only have 2 marks to be healing through during enrage.
While you loose dps he is hopefully not going to be getting healed > 30% while enraged.
I suggest trying this as a last resort, if you are getting more that 4 marks then you need to get your range/adds under control.
