Strategy
This encounter is a kiting encounter, where the tanks don't actually "tank" the boss. This is because the boss simply hits too hard. Instead, several ranged DPS will kite the boss around the room, while everyone else goes all out on the boss.
Phase 1-Kite (There is no Phase 2)
The key mechanic of this fight is Pheromones. The first player to get threat on the boss will start with this ability, and the boss will then fixate on that player. The player must kite the boss around the room, along the edge, and not get hit by the boss. While the player has the debuff the raid takes 20k (40k) nature damage per second while a player has Pheromones. This cannot be prevented.
Second, the player with the debuff will spawn pools on the ground every 2 seconds. Standing in this pools causes a player to take 50k (100k) damage from Pheromone Trail. These pools do not go away, so it is possible to run out of room if kiting is poor.
Lastly the player with the debuff gains a stack of Pungency every 2 seconds. Each stack increase the damage done by Pheromones by 10%. If the stacks get too high, then the raid will take too much damage to survive. The good news is Pheromones can be passed to another player if he/she gets into melee range of the player with the debuff. This removes the stacks. The bad news is the boss will Crush each time Pheromones is passed on normal mode, and the player giving the debuff cannot take it again for 2 minutes because of Pungency. To handle this, assign 5 players (ranged DPS) to rotate the debuff, where each player takes it for 30-40 seconds, meaning 15-20 stacks total. Healers will want to use raid cooldowns at 15 stacks in order to survive the pheremone damage.
In order to help the kiter the boss needs to be slowed. The boss has four Legs that can be damaged. Each leg has a blueish-green circle around them. Any player standing in one of these green circles gives the buff Weak Points, which increases the damage done to the legs by 100%. For each leg "killed," the boss gets a stack of Broken Leg, which slows the boss by 15% per stack and deals 3% of his maximum health. It's crucial that the DPS kill all legs as quickly as possible to slow the boss. Once the legs are down, they can resume DPS on the boss. Finally, the boss will use Mend Leg every 30 seconds. This heals one of the Legs to full and removes a stack of Broken Leg. The raid simply "kills" the Leg again and repeat.
To improve raid healing and reduce the chance of anyone being under the boss, the boss will be kited around the outer edge of the room in a clockwise fashion, while the raid stays near the middle and perpendicular to the boss. Melee DPS can be in the middle and slightly behind the boss to use abilities that require them to be behind. The kiting pattern is shown below.
A mechanic the that forces tanks into the encounter is Furious Swipe. This is a frontal cleave that does 600k (800k) physical damage. At least two people need to get hit by this, preferably tanks. Otherwise, the boss will gain the buff Fury, which increases his damage dealt and movement speed by 10% for 30 seconds. This buff stacks, and he does the attack about every 8 seconds, so it's important that both tanks are in front of the boss at all times.
His last main ability is Crush. When the boss appears, a purple circle appears underneath him. Anyone caught standing in this circle will cause the boss to use Crush, which does 150k (250k) damage to the whole raid and knocking them down and 800k damage to anyone inside the circle. The bottom line is don't stand in the purple circle.
Heroic Strategy
For the heroic fight, there are two key changes. First, the boss no longer uses Crush when players exchange Pheromones. Instead, the boss will peroidically Crush on his own. The raid should establish a cooldown rotation in order to survive and players with the Pheromones should use personal cooldowns to survive crush.
When the boss reaches 33% health, he gets Damaged. This does two things. 1. The boss no longer fixates the person with Pheromones 2. The boss must now be tanked like a normal boss and moves extremely fast
To meet the extremely strict berserk timer and survive the high raid damage, Phase 1 strategy must be adjusted from normal mode. First, Pheromone damage is too high to go to the usual 15 stacks. Therefore, each player in the rotation will exchange at 12 stacks. Because the debuff now lasts for 6 minutes, all DPS (including melee) should be prepared to be part of the rotation. Ranged DPS will start first, and then we will switch to melee DPS. Each player must call out when he/she has 8 stacks and so forth, so the next person in line can take the buff at the appropriate time. Healers will need to kite after the 30% health mark is reached.
Because of the high damage, the raid will need to stay in the middle as much as possible. This means all ranged DPS and healers should group up to maximize AoE healing. Melee may DPS the legs on the boss' right side, but they are not permitted to go to the other side to DPS the other legs. Otherwise, they risk getting out of range of healing and die. The compensate, the left legs will take passive damage as the fight progresses, but all damage on those legs should stop when they get low. That way, we can kill them later and cause the boss to lose 6% of his health instantly. This implies that the boss will be moving faster throughout Phase 1.
Once the boss reaches Phase 2, it becomes a simple tank and spank. Since raid damage is much smaller during this phase, healers will take over passing Pheromones, regardless of where the raid is in the order. All DPS will focus on the boss until it's at about 15% health. At this point, the raid should finish off all remaining legs to get quick damage on the boss and then finish off the last 3%.
